for Recombinant PIK3R1 proteinBackground

PIK3R1 (Phosphoinositide-3-Kinase Regulatory Subunit 1), also known as GRB1, p85-ALPHA or p85, is a regulatory subunit of phosphatidylinositol 3-kinase. It can bind to activated (phosphorylated) protein-Tyr kinases, through its SH2 domain, and acts as an adapter, mediating the association of the p110 catalytic unit to the plasma membrane. It is necessary for the insulin-stimulated increase in glucose uptake and glycogen synthesis in insulin-sensitive tissues. And it plays an important role in signaling in response to FGFR1, FGFR2, FGFR3, FGFR4, KITLG/SCF, KIT, PDGFRA and PDGFRB, likewise, plays a role in ITGB2 signaling. PIK3R1 also modulates the cellular response to ER stress by promoting nuclear translocation of XBP1 isoform 2 in a ER stress-and/or insulin-dependent manner during metabolic overloading in the liver and hence plays a role in glucose tolerance improvement.
