Product Specific Information
PA1-1058 detects a IRS-1 in mouse and human cells.
PA1-1058 has been successfully used in Western blot procedures. By Western blot this antibody detects an ~170 kDa protein representing IRS-1 in 3T3 L1 cell extract.
The PA1-1058 immunogen is a synthetic peptide corresponding to residues L(602) H T D D G Y M P M S P G V(615) of human IRS-1. The immunizing peptide is 92% conserved in rats, and mice. This peptide (Cat. # PEP-192) is available for use in neutralization and control experiments.
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.
