PCNA is a marker for cells in early G1 phase and S phase of the cell cycle. It is found in the nucleus and is a cofactor of DNA polymerase delta. It acts as a homotrimer and helps increase the processivity of leading strand synthesis during DNA replication. In response to DNA damage, PCNA is ubiquitinated and is involved in the RAD6-dependent DNA repair pathway. Two transcript variants encoding the same protein have been found for PCNA. Pseudogenes of this gene have been described on chromosome 4 and on the X chromosome.

sRANKL is a member of the tumor necrosis factor (TNF) cytokine family which is a ligand for osteoprotegerin and functions as a key factor for osteoclast differentiation and activation. This protein was shown to be a dentritic cell survival factor and is involved in the regulation of T cell-dependent immune response. T cell activation was reported to induce expression of this gene and lead to an increase of osteoclastogenesis and bone loss. This protein was shown to activate antiapoptotic kinase AKT/PKB through a signaling complex involving SRC kinase and tumor necrosis factor receptor-associated factor (TRAF) 6, which indicated this protein may have a role in the regulation of cell apoptosis.

Transmembrane receptor Patched regulates several developmental processes in both invertebrates and vertebrates. In higher vertebrates the patched (Ptc) also acts as a tumor suppressor. The patched receptor signaling involves negatively regulating a GPCR, smoothened. The binding Hedgehog ligand to Ptc removes the negative interaction of Ptc, and allows the signaling by smoothened. It has been shown that during head morphogenesis in D. melanogaster, Ptc positively interacts with smoothened, which leads to stimulation of Activin type 1 receptor Baboon, and activation of cell proliferation in the eye antennal disc. The expression of activated Baboon in the Ptc domain in Ptc mutant background completely abolish the head developmental defects.

Group I of the Metabotropic Glutamate Receptors includes GRM1 and GRM5, receptors that have been shown to activate phospholipase C. Alternative splice variants of GRM5 have been described, but their full-length nature has not been determined. Inflammation results in the activation of mGluR1 and mGluR5 in dorsal horn neurons of the spinal cord, leading to extracellular signal-regulated kinase (ERK) activation, which is required for nociceptive plasticity and enhanced pain. GRM5 is involved in inflammatory mechanical hyperalgesia and potentially in schizophrenia

GPR37 is an Orphan-A GPCR with an unknown ligand. GPR37 was recently identified as the PAEL receptor, a Parkin substrate involved in autosomal recessive juvenile Parkinson's (PDJ) disease. The PAEL receptor becomes unfolded, insoluble, and ubiquitinated when overexpressed, leading to unfolded protein-induced cell death. When the PAEL receptor is ubiquitinated by Parkin, it gets degraded, resulting in the suppression of cell death. The insoluble form of the PAEL receptor accumulates in the brains of PDJ patients and may cause selective neuronal death.

The Peroxiredoxin (Prdx, Prx, or Trx-Px) family of enzymes is a recently identified family of peroxidases found in free-living organisms. The six known isoforms (Prx1-6) play an important role in protecting lipids, enzymes and DNA against peroxides, such as hydrogen peroxide. The ubiquitously expressed peroxiredoxins have also been shown to play a role in apoptosis and cell differentiation. This is acomplished by the active cysteine of Prx reducing peroxides, which is then converted into a transient cysteine sulfenic acid or cysteine sulfinic acid. If Prx protection is inadequate against peroxidases, the resulting protein and DNA damage may result in neurological disease such as Alzheimer's or DNA damage leading to cancer.

The NOX family of NAPDH oxidases is comprised of seven transmembrane proteins that oxidize intracellular NAPDH/NADH, causing electron transport across the membrane and the reduction of molecular oxygen to superoxide. NOX3 is expressed predominantly in the inner ear and is involved in the biogenesis of otoconia/otolith. It has been suggested that NOX3 is activated by the Transient Receptor Potential Vanilloid 1 (TRPV1), and this activity causes increased levels of reactive oxygen species in the inner ear, which in turn leads to STAT1-mediated inflammation and hearing loss.

STK39 is a serine/threonine kinase that is thought to function in the cellular stress response pathway. The kinase is activated in response to hypotonic stress, leading to phosphorylation of several cation-chloride-coupled cotransporters. The catalytically active kinase specifically activates the p38 MAP kinase pathway, and its interaction with p38 decreases upon cellular stress, suggesting that this kinase may serve as an intermediate in the response to cellular stress.This gene encodes a serine/threonine kinase that is thought to function in the cellular stress response pathway.

Infectious diseases are the leading cause of death worldwide. AIDS, tuberculosis (TB), malaria, diarrhoeal and respiratory infections account for 78% of deaths caused by infectious disease. As many infectious diseases are controlled, new diseases emerge and old diseases become resistant to current drugs. Many infectious diseases have been associated with an increase risk of carcinoma. Influenza continues to attract researchers as new strains appear by the ability of the influenza gene to mix with different forms of the virus. Recently, research on SARS and West Nile virus has risen due to the increased number of infections. These antibodies assist in research by detecting the infectious disease agent.

CXXC5 Antibody: CXXC5 is zinc finger protein closely related to the DVL1-binding protein CXXC4 (also known as Idax), and like CXXC4 is thought to modulate the Wnt signaling pathway during development. CXXC5 is upregulated in neural stem cells upon BMP4 stimulation, leading to decreased levels of the Wnt-signaling target AXIN2 and facilitated the response of the stem cells to Wnt3a. Recent reports suggest CXXC5 transcription is activated by the Wilms tumor 1 (WT1) transcription factor, and together are involved in the WNT/beta-catenin pathway and play a role in embryonic kidney development.

Two Beclin-1-interacting proteins, the run domain Beclin-1 interacting and cysteine-rich containing protein (Rubicon) and ATG14L, reciprocally regulate autophagy at different stages. Knockdown of Rubicon caused enhancement of autophagy while that of ATG14L caused a defect in autophagosome formation. Rubicon functions as part of a Beclin-1-PIK3C3-containing autophagy complex and is also an essential, positive regulator of the NAPDH oxidase complex. Upon microbial infection or TLR2 activation, Rubicon interacts with the CYBA subunit of the NAPDH oxidase complex, leading to a burst of reactive oxygen species and inflammatory cytokines.

Ephrin-A4 (EFNA4) is also known as EPH-related receptor tyrosine kinase ligand 4 (LERK4), EPLG4, which belongs to the ephrin family. EFNA4 contains one ephrin RBD (ephrin receptor-binding) domain. EFNA4 is cell surface GPI-bound ligand for Eph receptors, a family of receptor tyrosine kinases which are crucial for migration, repulsion and adhesion during neuronal, vascular and epithelial development. EFNA4 binds promiscuously Eph receptors residing on adjacent cells, leading to contact-dependent bidirectional signaling into neighboring cells. EFNA4 may play a role in the interaction between activated B-lymphocytes and dendritic cells in tonsils.

Netrin-1 controls guidance of CNS commissural axons and peripheral motor axons. Its association with either DCC or some UNC5 receptors will lead to axon attraction or repulsion, respectively. It also serve as a survival factor via its association with its receptors which prevent the initiation of apoptosis. Netrin-1 is also Involved in tumorigenesis by regulating apoptosis. Netrin-1 promotes atherosclerosis by retaining macrophages in the artery wall. Netrin-1 also governs induced pluripotent stem cell (iPS) formation and improves reprogramming efficiency of human and mouse somatic cells by limiting apoptosis mediated by Netrin-1 receptors DCC or UNC5b.

DYRK1A Antibody: DYRK1A is a member of the dual-specificity tyrosine phosphorylation-regulated kinase (DYRK) family and is thought to be involved in neuronal differentiation, neurodegenerative diseases, and is considered to be a strong candidate gene for learning defects associated with Down syndrome. DYRK1A phosphorylates several transcription factors such as p53, leading to inhibition of embryonic neuronal cell proliferation. DYRK1A associates with multiple proteins, including SPRED1 and SPRED2; this association appears to inhibit the phosphorylation activity of DYRK1A. Recent evidence also suggests that DYRK1A may be involved in the replication of HIV-1.
