The antiserum was produced against a chemically synthesized phosphopeptide derived from the region of human IRS-1 that contains tyrosine 612. The sequence is conserved in mouse, rat and chicken. if (typeof window.$mangular === undefined || !window.$mangular) { window.$mangular = {}; } $mangular.antigenJson = \[{targetFamily:IRS1,uniProtId:P35568-1,ncbiNodeId:9606,antigenRange:612,antigenLength:1242,antigenImageFileName:44-816G_IRS1_P35568-1_Rabbit.svg,antigenImageFileNamePDP:44-816G_IRS1_P35568-1_Rabbit_PDP.jpeg,sortOrder:1}\]; $mangular.isB2BCMGT = false; $mangular.isEpitopesModalImageMultiSizeEnabled = true;

Product Specific Information

On western blotting this antibody detects a protein with the apparent MW of 165 kDa. Positive controls used were Insulin (50 nM for 5 minutes) or TPA (100 ng/mL for 30 min) treated human embryonic kidney cells (293T) or Chinese Hamster Ovary cells (CHO-T) transiently transfected with a plasmid encoding human IRS1.

Target Information

IRS-1, a major substrate of the insulin receptor, is phosphorylated in response to stimulation of cells by insulin, insulin-like growth factor 1 (IGF-1) and interleukin 4 (IL-4). IRS-1 is phosphorylated on serine, threonine and tyrosine residues in a variety of tissues. An insulin-sensitive serine/threonine kinase casein kinase II mediates a portion of the insulin-stimulated serine/threonine phosphorylation of overexpressed IRS-1 in vivo. Thr 502 is identified as the major casein kinase II-catalyzed phosphorylation site in rat IRS-1, and Ser 99 is an additional phosphorylation site catalyzed by casein kinase II. Thus, casein kinase II-catalyzed phosphorylation of IRS-1 may be a component of the intracellular insulin signaling cascade. IRS-1 contains three putative binding sites for 14-3-3 (Ser 270, Ser 374 and Ser 641) and the motif around Ser 270 is located in the phosphortyrosine binding domain of IRS-1, which is responsible for the interaction with the insulin receptor.
