EMAP II (Endothelial monocyte-activating polypeptide 2) is a pro-inflammatory cytokine and participant in apoptotic cell death. It is synthesized as a precursor (pro-EMAP II), lacking a secretion signal peptide. In apoptotic cells, the ~34 kDa pro-form of EMAP II is cleaved by Caspase-7 (and Caspase-3 to a lesser extent) at aspartate 144 to its mature, ~20 kDa form. The mature form of EMAP II has been found to have many different functions. In vivo, it recruits leukocytes to the site of apoptotic cell death. In vitro it has been shown to activate endothelial cells (and the release of von Willebrand factor, E-selectin and P-selectin), neutrophils, and induces macrophage expression of TNFa and TF (tissue factor). EMAP II is also a possible biomarker for brain injury, having been found to be differentially expressed in two types: traumatic injury shows an increase and ischemic injury shows a decrease in EMAP II expression (Dave, et al, 2014).

Interleukin-22(IL-22) is a member of a group of the IL-10 family, a class of potent mediators of cellular inflammatory responses. IL-22 is produced by activated DC and T cells. IL-22 and IL-10 receptor chains play a role in cellular targeting and signal transduction. It can initiate and regulate innate immune responses against bacterial pathogens especially in epithelial cells such as respiratory and gut epithelial cells. IL-22 along with IL-17 likely plays a role in the coordinated response of both adaptive and innate immune systems. IL-22 also promotes hepatocyte survival in the liver and epithelial cells in the lung and gut similar to IL-10. Biological activity of IL-22 is initiated by binding to a cell-surface complex consisting of IL-22R1 and IL-10R2 receptor chains. IL-22 biological activity is further regulated by interactions with a soluble binding protein, IL-22BP. IL-22BP and an extracellular region of IL-22R1 share sequence similarity. In some cases, the pro-inflammatory versus tissue-protective functions of IL-22 are regulated by cytokine IL-17A.

Lysosome membrane protein II (LIMPII)，also known as SCARB2, is a type III multi-pass membrane glycoprotein that is located primarily in limiting membranes of lysosomes and endosomes on all tissues and cell types so far examined. Earlier studies in mice and rat suggested that this protein may participate in membrane transportation and the reorganization of endosomal/lysosomal compartment. The protein deficiency in mice was reported to impair cell membrane transport processes and cause pelvic junction obstruction, deafness, and peripheral neuropathy. Further studies in human showed that this protein is identified as a receptor for EV71 (human enterovirus species A, Enterovirus 71) and CVA16 (coxsackievirus A16) which are most frequently associated with hand, foot and mouth disease (HFMD). Mutations in this gene caused an autosomal recessive progressive myoclonic epilepsy-4 (EPM4), also known as action myoclonus-renal failure syndrome (AMRF). Alternatively spliced transcript variants encoding different isoforms have been found for this gene. In addition, LIMPII also has been shown to bind thrombospondin-1, may contribute to the pro-adhesive changes of activated platelets during coagulation, and inflammation.

Programmed Death-1 (PD-1), firstly cloned from mouse T cell hybridoma 2B4.11, is one member of CD28/CTLA-4 superfamily. PD-1 belongs to type I transmembrane protein and acts as an important immunosuppressive molecule. The cytoplamsic tail of PD-1 contains two structural motifs, an immunoreceptor tyrosine-based inhibitory motif (ITIM) and an immunoreceptor tyrosine-based switch motif (ITSM) formed by two tyrosine residues which make the difference in PD-1 signal mediating. Mouse PD-1 is expressed in thymus and shares about 69% aa sequence identity with human PD-1. Recently, programmed death-1 (PD-1) with its ligands, programmed death ligand B7H1 (PD-L1) and B7DC (PD-L2), was found to regulate T-cell activation and tolerance, upon ligand binding, inhibiting T-cell effector functions in an antigen-specific manner. PD-1 gene knocked out mice would induce some autoimmune diseases, which suggests that PD-1 acts as a co-inhibitory molecule actively participating in maintaining peripheral tolerance. Thus, PD-1 may be a useful target for the immunologic therapy of carcinoma,infection,autoimmune diseases as well as organ transplantation.

The UCHT1 antibody is specific for human CD3e, also known as CD3 epsilon, a 20 kDa subunit of the T cell receptor complex, along with CD3 gamma and CD3 delta. These integral membrane protein chains assemble with additional chains of the T cell receptor (TCR), as well as CD3 zeta chain, to form the T cell receptor – CD3 complex. Together with co-receptors CD4 or CD8, the complex serves to recognize antigens bound to MHC molecules on antigen-presenting cells. These interactions promote T cell receptor signaling (T cell activation), inducing cell proliferation, differentiation, production of cytokines or activation-induced cell death. CD3 is differentially expressed during thymocyte-to-T cell development and on all mature T cells.

Four distinct colony-stimulating factors (CSFs) that promote survival, proliferation and differentiation of bone marrow precursor cells have been well characterized: granulocyte macrophage CSF (GMCSF), granulocyte CSF (GCSF), macrophage CSF (MCSF), and Interleukin-3 (IL-3, Multi CSF). Both GMCSF and IL-3 are multipotential growth factors, stimulating proliferation of progenitor cells from more than one hematopoietic lineage. In contrast, GCSF and MCSF are lineage restricted hematopoietic growth factors, stimulating final mitotic divisions and the terminal cellular maturation of the partially differentiated hematopoietic progenitors. Macrophage CSF, also known as CSF1, is produced by monocytes, fibroblasts and endothelial cells. It stimulates the formation of macrophage colonies, enhances antibody-dependent, cell-mediated cytotoxicity by monocytes and macrophages, and inhibits bone resorption by osetoclasts. Natural human MCSF is a dimeric glycoprotein of 70-90 kD molecular weight, existing in multiple glycosylation forms. It binds to a 165 kD glycoprotein of the receptor tyrosine kinase subclass III, a family that includes the receptors for platelet derived growth factor (PDGF) and stem cell factor (SCF).

Superoxide dismutase (SOD) is responsible for the elimination of cytotoxic active oxygen by catalyzing the dismutation of the superoxide radical to oxygen and hydrogen peroxide. There are three SOD isoenzymes in mammalian cells. They are: extracellular SOD (EC SOD), copper and zinc-containing SOD (Cu/Zn SOD) and manganese-containing SOD (Mn SOD). The Cu/Zn form contains Cu and Zn ions and exists as a 32 kDa dimer in the cytosol. Mn SOD is an 80 kDa tetramer that contains Mn ion and resides in the mitochondrial matrix. Mn SOD is a tumor necrosis factor (TNF)-inducible enzyme that protects cells from TNF-mediated apoptosis via superoxide anion detoxification and the subsequent regulation of apoptosis through cytochrome c release and the modulation of the redox state of the mitochondria. Mn SOD has also been shown to be a tumor suppressor in human breast cancer. Overexpression of this enzyme protects neurons from NMDA- and nitric oxide-induced neurotoxicity.

Lysosomal enzymes containing one or two mannose 6-phosphate (man6P) moieties are moved about in the cell by two distinct but interconnected cycles by means of 300 kDa cation-independent mannose 6-phospate receptors (MPR). MPR cycles and transports newly synthesized lysosomal enzymes between the TGN and late endosomes / early lysosomes. It also cycles and transports extracellular lysosomal enzymes between the plasma membrane and early endosomes via clathrin coated vesicles. The bulk of the MPR protein is in the extracellular/lumenal domain. The entire pool of MPRs cycles between these cellular compartments every 3 hours. The steady state distribution of MPR's is predominantly within late endosomes, fewer in the trans Golgi network and ~5-10 % at the cell surface. In addition to its man6P binding activity, the MPR contains a separate binding site for the type II insulin-like growth factor and is capable of binding both man6P and IGF-II simultaneously. An ~240 kDa soluble, truncated form, representing the extracellular domain of the protein, has also been found circulating in serum and is capable of binding both ligands.

Methylation of DNA at cytosine residues plays an important role in regulation of gene expression, genomic imprinting and is essential for mammalian development. Hypermethylation of CpG islands in tumor suppressor genes or hypomethylation of bulk genomic DNA may be linked with development of cancer. To date, 3 families of mammalian DNA methyltransferase genes have been identified which include Dnmt1, Dnmt2 and Dnmt3. Dnmt1 is constitutively expressed in proliferating cells and inactivation of this gene causes global demethylation of genomic DNA and embryonic lethality. Dnmt2 is expressed at low levels in adult tissues and its inactivation does not affect DNA methylation or maintenance of methylation. The Dnmt3 family members, Dnmt3a and Dnmt3b, are strongly expressed in ES cells but their expression is down regulated in differentiating ES cells and is low in adult somatic tissue. Dnmt 1 co-purifies with the retinoblastoma (Rb) tumour suppressor gene product, E2F1, and HDAC1. Dnmt 1 also cooperates with Rb to repress transcription from promoters containing E2F binding sites suggesting a link between DNA methylation, histone deacetylase and sequence-specific DNA binding activity, as well as a growth-regulatory pathway that is disrupted in nearly all cancer cells.

Human Vascular endothelial growth factor receptor 1(VEGFR-1, FLT-1) is a member of the the class III subfamily of receptor tyrosine kinases (RTKs) and Tyr protein kinase family and CSF-1/PDGF receptor subfamily. VEGFR-1 is widely expressed in human tissues including normal lung, placenta, liver, kidney, heart and brain tissues. It is specifically expressed in most of the vascular endothelial cellsand peripheral blood monocytes. VEGFR-1 contains seven Ig-like C2-type domains and one protein kinase domain. VEGFR-1is an essential receptor tyrosine kinase and plays an important role in theregulation of VEGF family-mediated vasculogenesis, angiogenesis, and lymphangiogenesis. It is also mediators of neurotrophic activity and regulators of hematopoietic development. VEGFR-1 is a receptor for VEGF, VEGFB and PGF. It has a tyrosine-protein kinase activity. Tyrosine-protein kinase that acts as a cell-surface receptor for VEGFA, VEGFB and PGF.It may play an essential role as a negative regulator of embryonic angiogenesis by inhibiting excessive proliferation of endothelial cells and promote endothelial cell proliferation, survival and angiogenesis in adulthood. Its function in promoting cell proliferation seems to be cell-type specific. VEGFR-1 can also promote PGF-mediated proliferation of endothelial cells, proliferation of some types of cancer cells, but does not promote proliferation of normal fibroblasts (in vitro).

Initiation of transcription by RNA polymerase II requires the activities of more than 70 polypeptides. The protein that coordinates these activities is transcription factor IID (TFIID), which binds to the core promoter to position the polymerase properly, serves as the scaffold for assembly of the remainder of the transcription complex, and acts as a channel for regulatory signals. TFIID is composed of the TATA-binding protein (TBP) and a group of evolutionarily conserved proteins known as TBP-associated factors or TAFs. TAFs may participate in basal transcription, serve as coactivators, function in promoter recognition or modify general transcription factors (GTFs) to facilitate complex assembly and transcription initiation. This gene encodes TBP, the TATA-binding protein. A distinctive feature of TBP is a long string of glutamines in the N-terminus. This region of the protein modulates the DNA binding activity of the C terminus, and modulation of DNA binding affects the rate of transcription complex formation and initiation of transcription. The number of CAG repeats encoding the polyglutamine tract is usually 32-39, and expansion of the number of repeats increases the length of the polyglutamine string and is associated with spinocerebellar ataxia 17, a neurodegenerative disorder classified as a polyglutamine disease. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq]

RAS proteins are signal-transducing, guanine nucleotide-binding proteins that appear to function as a branchpoint in signal transduction. RAS coordinates the activity of multiple signalling pathways, regulating diverse cellular functions including cell growth, differentiation and apoptosis. The human RAS gene family consists of three identified members which encode proteins of 21 kDa. Human cH RAS and cK RAS are the cellular homologs of vH- and vK RAS originally isolated from Harvey and Kirsten strains of rat sarcoma viruses. The third family member is designated cN RAS. Normal cellular ras genes are referred to as protooncogenes and have the potential for activation to oncogenes by mutations occurring in codons 12, 13 and 61. Such mutated, activated and transforming ras genes have been identified and isolated from human tumors and cultured tumor cells. Although the expression patterns of ras proto-oncogene proteins in normal human tissues are known, similar information for activated ras oncogene encoded p21s and their relevance to human disease diagnosis and prognosis remains to be determined.

The serum amyloid A (SAA) family comprises a number of differentially expressed lipoproteins, acute-phase SAA1 and SAA2, the former being a major component in plasma, and constitutive SAA's (C-SAAs). Although the liver is the primary site of synthesis of both SAA types, extrhepatic production has been reported. The in-vivo concentrations increase by as much as 1000 fold during inflammation. Several studies have expressed it's importance in the diagnosis and monitoring of various diseases. Pathological SAA values are often detected in association with normal CRP concentrations. SAA rises earlier and more sharply than CRP.SAA enhances the binding of HDL's to macrophages and thus helps the delivery of lipid to sites of injury for use in tissue repair. It is thus thought to be an integral part of the disease process. In addition, recent experiments suggest that SAA may play a "houekeeping" role in normal human tissues.Elevated levels of SAA over time predispose secondary amyloidosis, extracellular accumulation of amyloid fibrils, derived from a circulating precursor, in various tissues and organs. The most common form of amyloidosis occurs secondary to chronic inflammatory disease, particularly rheumatoid artheritis.

Camelids produce functional IgG isotypes that do not incorporate light chains. Comparative studies of old world camelids (Camelus bactrianus and Camelus dromedarius) and new world camelids (Lama pacos, Lama glama and Lama vicugna) have shown that heavy-chain-only immunoglobulins represent between 35% - 70% of total IgG in the sera of all species. At present, three subclasses of camelid IgG have been identified (IgG1, IgG2, IgG3), of which IgG2 and IgG3 lack the light chains. IgG1 binds strongly to protein A and G, is composed of conventional antibodies, and totals 25 % of serum IgG. Llama IgG1 antibodies migrate as a 150-kDa protein in SDS-polyacrylamide gel under non-reducing conditions. Under reducing conditions, IgG1 antibodies split into four proteins (two of each H- and L-chains), which gives protein bands of about 52-55 kDa (H-chain) and about 27 kDa (L-chain). Anti-Llama IgG1 generated in rabbit detects specifically the Llama IgG1 isotype. This anti-Llama secondary Antibody is suitable for western blot, ELISA, ChIP and immunohistochemistry as well as other more general immunoassays.

Arginine methylation is an irreversible post translational modification which has only recently been linked to protein activity. At least three types of PRMT enzymes have been identified in mammalian cells. These enzymes have been shown to have essential regulatory functions by methylation of key proteins in several fundamental areas. These protein include nuclear proteins (Histone 2A, 3, 4), IL enhancer binding factor, nuclear factors (NF45, 90, ILF3, Nucleolin, STAT1, Poly(A) binding protein II), cell cycle proteins (phosphoprotein phosphatase 2A), signal transduction proteins (FGF2, Fibrillarin, FN, INFAR1, Jak, MBP, Src-adaptor Sam68), apoptosis proteins (FADD, ICE-like protease), and viral proteins (Hepatitis C NS3 RNA Helicase, HIV TAR). The mammalian PRMT family currently consists of 5 members that share two large domains of homology. Outside of these domains, epitopes were identified and antibodies against all five PRMT members have been developed. These antibodies can be utilized to explore arginine methylation and its regulatory functions.

The description of specific intranuclear structures known today as Cajal bodies was first published in 1903 by the neuro-cytologist Ramon-y-Cajal. He observed that neurons stained with silver contained spherical structures of around 0.5 micron in diameter that were often associated with nucleoli and called them nucleolar accessory bodies. Later, the same bodies were called coiled bodies since when these structures were viewed by electron microscopy, they resembled a tangle of coiled threads. It was found that patients with autoantibodies against coiled bodies recognize a protein of 80 kDa termed p80-coilin. Using these antibodies, coiled bodies were identified in plants, flies, frogs, birds, and mammals. The gene encoding p80-coilin has been cloned and sequenced. It contains two nuclear localization sequences (NLS) (at amino acid 107-112 and 181-198) and several serine residues that are phosphorylated in vivo. Mutating Serine-202 to Aspartate causes the disappearance of coiled bodies and a redistribution of coilin to intranucleolar domains. Nuclear antigens shown to colocalize with p80 coilin in Cajal bodies include basal transcription factors, cell cycle factors (cdks), splicing snRNPs and nucleolar factors including snoRNPs.
