Matrix metalloproteinases (MMPs) belong to a family of secreted or membrane-associated zinc endopeptidases capable of digesting extracellular matrix components. MMP-14 (MT1-MMP), membrane-type MMP, plays an important role in tumor invasion. MMP-14 is expressed on the surface of invasive tumor cells, in stromal cells of human colon, breast, and head and neck carcinomas. MMP-14 is secreted as zymogen with a prodomain, a catalytic domain, a hinge region, a hemopexin-like domain, and a transmembrane domain. It can activate pro-MMP-23 and degrade a variety of substrates, including fibrillar collagens I, II, III, fibronectin, vitronectin and laminin-1.

A truncated human MMP-14 with His-tag was expressed in E. coli. The Mr on SDS-PAGE is 31-kDa. Incubation with 1 mM APMA at 37°C for 2 hr will activate MMP-14. Its activity can be measured by FRET peptides

TAO (thousand and one amino acid) protein kinases mediate signaling from carbachol to p38 MAPK and ternary complex transcription factors. This has led to the proposal that the TAO protein kinases play an essential role in signaling from physiological agonists to the stress-responsive p38 MAPKs. Autophosphorylation of TAO may play a role in the mechanism of TAO activation. The MEK binding domain of TAO is autophosphorylated on both serine and threonine residues and Ser181 is located within this domain.

The protein encoded by this gene is a member of the cyclin-dependent protein kinase (CDK) family. CDK family members are highly similar to the gene products of Saccharomyces cerevisiae cdc28, and Schizosaccharomyces pombe cdc2, and are known to be important regulators of cell cycle progression. This kinase and its regulatory subunit cyclin C are components of the RNA polymerase II holoenzyme complex, which phosphorylates the carboxy-terminal domain (CTD) of the largest subunit of RNA polymerase II. This kinase has also been shown to regulate transcription by targeting the CDK7/cyclin H subunits of the general transcription initiation factor IIH (TFIIH), thus providing a link between the 'Mediator-like' protein complexes and the basal transcription machinery.

Cochlin is an extracellular matrix protein expressed in the cochlea and vestibule of the inner ear. Mutations in the cochlin gene are linked to the autosomal-dominant DFNA9 syndrome, a disorder characterized by hearing loss. Cochlin is also expressed in follicular dendritic cells of the spleen and the lymph nodes. The N-terminus of cochlin contains a LCCL domain also present in Factor C, a serine protease of the horseshoe crab Limulus, involved in activating the coagulation cascade in response to LPS. A recent study showed that in response to inflammation, LPS or bacterial infection, cochlin is cleaved by the proteases aggrecanases and secreted into blood circulation. The secreted cochlin (LCCL domain) seems to have a role in local cytokine production, recruitment of immune effector cells and bacterial clearance. Cochlin is secreted as two forms p8 and p18, whereas p18 being the glycosylated form of p8.

LIF has the capacity to induce terminal differentiation in leukemic cells. Its activities also include the induction of hematopoietic differentiation in normal and myeloid leukemia cells, the induction of neuronal cell differentiation and the stimulation of acute-phase protein synthesis in hepatocytes. LIF activates JAK & STAT signaling in human embryonic stem (ES) cells, but this pathway does not maintain pluripotency in these cells, which instead rely on FGF2-mediated ERK signaling. By contrast, mouse ES cells can be maintained by LIF-mediated JAK & STAT signaling. LIF binds to a high affinity heterodimeric receptor complex consisting of two proteins: LIF-R alpha that binds LIF with low affinity and the 130kDa (gp130) subunit that by itself does not bind LIF, but is required for high affinity binding of LIF.

ANGPTL-3 (Angiopoietin-like protein 3) is a member of the angiopoietin family of structurally related proteins, characterized by a coiled N-terminal domain and a C-terminal fibrinogen-like domain. It is primarily expressed in the liver, and can exert activities related to both angiogenesis and lipid metabolism. ANGPTL-3 inhibits lipoprotein lipase (LPL) and endothelial lipase (EL), which has the effect of increasing plasma levels of triglycerides and HDL-associated cholesterol. The fibrinogen-like portion of the ANGPTL-3 protein can bind alpha-5/beta-3 integrins, leading to endothelial cell adhesion and migration. Recombinant Human ANGPTL-3 is a glycoprotein that migrates by SDS-PAGE analysis at an apparent molecular weight of 62 kDa, and contains 452 amino acid residues including a C-terminal His tag. The calculated molecular weight of Recombinant Human ANGPTL-3 is 52.9 kDa.

Flt3-Ligand is a growth factor that regulates proliferation of early hematopoietic cells. Flt3-Ligand binds to cells expressing the tyrosine kinase receptor Flt3. Flt3-Ligand, by itself does not stimulate proliferation of early hematopoietic cells, but synergizes with other CSFs and interleukins to induce growth and differentiation. Unlike SCF, Flt3-Ligand exerts no activity on mast cells. Multiple isoforms of Flt3-Ligand have been identified. The predominant biologically active form is anchored to the cell surface as the extracellular domain of a transmembrane protein (209 a.a.). The membrane-bound isoform can be proteolytically cleaved to generate a biologically active soluble isoform. Recombinant Human Flt3-Ligand is a soluble 17.6 kDa protein consisting of 155 amino acid residues.

Mammalian mitochondrial ribosomal proteins are encoded by nuclear genes and help in protein synthesis within the mitochondrion. Mitochondrial ribosomes (mitoribosomes) consist of a small 28S subunit and a large 39S subunit. They have an estimated 75% protein to rRNA composition compared to prokaryotic ribosomes, where this ratio is reversed. Another difference between mammalian mitoribosomes and prokaryotic ribosomes is that the latter contain a 5S rRNA. Among different species, the proteins comprising the mitoribosome differ greatly in sequence, and sometimes in biochemical properties, which prevents easy recognition by sequence homology. MRPS24 encodes a 28S subunit protein. A pseudogene corresponding to this gene is found on chromosome 11. [provided by RefSeq].

Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Nucleosomes consist of approximately 146 bp of DNA wrapped around a histone octamer composed of pairs of each of the four core histones (H2A, H2B, H3, and H4). The chromatin fiber is further compacted through the interaction of a linker histone, H1, with the DNA between the nucleosomes to form higher order chromatin structures. This gene is intronless and encodes a member of the histone H3 family. Transcripts from this gene lack polyA tails; instead, they contain a palindromic termination element. This gene is located separately from the other H3 genes that are in the histone gene cluster on chromosome 6p22-p21.3. [provided by RefSeq].

Tumor necrosis factor (TNF, cachexin or cachectin and formerly known as tumor necrosis factor-alpha) is a cytokine involved in systemic inflammation and is a member of a group of cytokines that stimulate the acute phase reaction. The receptor TNF-R1 is activated by both the membrane-bound and soluble trimeric forms of TNF-alpha, whereas the receptor TNF-R2 only responds to the membrane-bound form of TNF-alpha (MultimericTNF-alpha (Prod. No. AG-40B-0019). Since the MultimericTNF-alpha mimics the membrane-bound form (forms oligomers higher than trimer), it is the only TNF-alpha protein that can activate the TNF-R2. For TNF-R1 activation, either "normal" TNF-alpha or MultimericTNF-alpha can be used.

BICD1 was initially identified as the human homolog to Drosophila Bicaudal-D protein that forms part of the cytoskeleton and mediates the correct sorting of mRNAs for oocyte- and axis-determining factors during oogenesis. BICD1 can bind to dynein-dynactin and co-localizes with Rab6A on the trans-Golgi network and cytoplasmic vesicles, suggesting BICD1 regulates COPI-independent Golgi-ER transport. BICD1 will also interact with Rab6B, a Rab6 isoform that is expressed primarily in brain. Live cell imaging showed bi-directional movement of Rab6B structures in SK-N-SH neurites, indicating that BICD1 is involved in the Rab6B regulation of retrograde cargo transport in neuronal cells.

Chromatin condensation and nuclear fragmentation (CCNF) is the hallmark of apoptosis. CCNF is triggered by the activation of members of caspase family, caspase activated DNase (CAD/DFF40), and several novel proteins including AIF and CIDE. A new inducer of chromatin condensation was recently identified and designated Acinus (for apoptotic chromatin condensation inducer in the nucleus). Acinus is cleaved by caspase-3 and an additional unknown protease generating a small active peptide p17, which causes chromatin condensation in vitro when it is added to purified nuclei. Acinus also induces apoptotic chromatin condensation in cells. Acinus is ubiquitously expressed. Three different spliced forms of Acinus have been identified in human and mouse and designated AcinusL, AcinusS and AcinusS'.

It recognizes a protein of 75kDa, identified as Thrombomodulin. Thrombomodulin is a transmembrane glycoprotein with natural anticoagulant properties. It is normally expressed by a restricted number of cells, such as endothelial and mesothelial cells. In addition, synovial lining and syncytio-trophoblasts of placenta also express thrombomodulin. This protein is present in almost all of benign vascular tumors and majority of malignant vascular tumors (Kaposi s sarcoma, angiosarcoma, and epithelioid hemangioendothelioma). Hence, anti-thrombomodulin serves as a sensitive marker for lymphatic endothelial cells and their tumors. Recently, thrombomodulin antibody has been used for mesothelial cells and malignant mesotheliomas.
