Description générale
Insulin receptor substrate-1 (IRS-1) is among the four IRS proteins (IRS-1-IRS-4) that mediate signalling by insulin receptor (IR) and insulin-like growth factor (IGF) receptor. IRS-1 has a pleckstrin homology domain and a phosphotyrosine-binding domain. Phosphorylation of the Tyr1179 residue in the SH-1 negatively regulates insulin. IRS-1 has the abililty to translocate to the nucleus, the mechanism of which is not very clear. Estrogen receptors (ER) α and β have a strong affinity to IRS-1, an important interaction in breast cancers and medulloblastomas. [1] The expression of IRS-1 in prostate cancer is associated with lower tumor cell invasiveness. Along with ER α, IRS-1 also modulates transcriptional activity involved in the development of breast and prostate cancer. [1] The signalling pathway involving IGF-IR-IRS-1 in cells expressing JCV T-antigen has been reported to affect the proliferation, survival and DNA repair in the cells. Phosphorylation of IRS-1 at Ser312 and Ser616 results in the negative regulation of insulin signalling in humans
Anti-phospho-IRS-1 (pSer312) specifically recognizes human IRS-1 (pSer312). It may react with mouse and rat (100% homology) IRS-1.

Immunogène
synthetic phosphopeptide derived from the region of IRS-1 that contains serine 312. This sequence is 100% homologous with mouse and rat IRS-1.
Application
Anti-phospho-IRS-1 (pSer312) antibody may be used for detection by immunoblotting, in stimulated CHO cell line expressing human insulin receptor, at a working dilution of 1:1000.
Forme physique
Solution in Dulbecco′s phosphate buffered saline (without Mg2+ and Ca2+), pH 7.3 containing 50% glycerol, 1.0 mg/mL BSA (IgG, protease free) and 0.05% sodium azide.

Serine phosphorylation of insulin receptor substrate-1 (IRS-1) inhibits insulin signal transduction in a variety of cell backgrounds, which might contribute to peripheral insulin resistance. However, because of the large number of potential phosphorylation sites, the mechanism of inhibition has been

JC polyomavirus (JCV), which infects 90% of the human population, is detectable in human tumors. Its early protein, JCV T-antigen, transforms cells in vitro and is tumorigenic in experimental animals. Although T-antigen-mediated transformation involves genetic alterations of the affected cells

This work sought to compare aqueous angiographic segmental patterns with bead-based methods which directly visualize segmental trabecular meshwork (TM) tracer trapping. Additionally, segmental protein expression differences between aqueous angiographic-derived low- and high-outflow human TM regions were evaluated. Post-mortem human eyes
