[https://www.uniprot.org/uniprot/P85A_BOVIN P85A_BOVIN] Binds 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. Necessary for the insulin-stimulated increase in glucose uptake and glycogen synthesis in insulin-sensitive tissues. 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 (By similarity).

SH3 domains are found in proteins associated with receptor tyrosine kinase signal transduction complexes. The solution structure of the SH3 domain of the 85 kd regulatory subunit of phosphatidylinositol 3-kinase is shown to be a compact beta barrel consisting of five beta strands arranged in two beta sheets of three and two strands. The structure is similar to that of chicken brain alpha spectrin but represents a distinct class of SH3 domain, with an insertion between the second and third beta strands that may influence binding specificity. 1H chemical shift changes induced by complex formation with a synthetic peptide derived from the SH3-binding protein dynamin, together with amino acid sequence comparisons, suggest that the ligand-binding site consists of a hydrophobic surface flanked by two charged loops.
