a G-beta like protein containing 7 WD domains. A presumptive scaffold protein, linking protein kinase C to its substrates. Binds inositol 1,4,5-trisphosphate receptors and regulates Ca2+ release by enhancing inositol 1,4,5-trisphosphate receptor binding affinity for inositol 1,4,5-trisphosphate. An insulin-like growth factor 1 receptor-interacting protein that can regulate IGF-1-mediated Akt activation and protection from cell death. Note: This description may include information from UniProtKB.
