Background: IRS2

IRS2 (insulin receptor substrate 2) is a 180-190 kDa substrate intermediate that lies between various cytokine receptors and downstream signaling molecules. It is the primary IRS protein found in hematopoietic cells. Depending upon the receptor, IRS2 undergoes phosphorylation, either via Tyk2 following type I IFN binding, or via JAK1 and 3 following IL-4, -7 and -15 binding. This event allows for its subsequent association with PI-3 kinase. Human IRS2 is 1338 amino acids (aa) in length with a predicted MW of 138 kDa. It contains one PH (pleckstrin homology) domain (aa 16-144), followed by a PTB (phosphotyrosine-binding)domain (aa 194-298) and seven YxxM (Tyr/x/x/Met) motifs (aa 540-1075). IRS2 is phosphorylated on multiple Ser and Tyr residues. There are two potential splice variants. One shows a 16 aa substitution for the C-terminal Glu, while another shows an 11 aa substitution for aa 1314-1338. Over aa 1035-1136, human IRS2 shares 86% aa identity with mouse IRS2.
