Summary

Description
May mediate the control of various cellular processes by insulin. When phosphorylated by the insulin receptor binds specifically to various cellular proteins containing SH2 domains such as phosphatidylinositol 3-kinase p85 subunit or grb2. Activates phosphatidylinositol 3-kinase when bound to the regulatory p85 subunit (By similarity).

Subunit
Interacts with the NPXY motif of tyrosine-phosphorylated igf1r and insr via the PTB domain. Binds to phosphatidylinositol 3-kinase p85 subunit at a low level in vitro prior to phosphorylation. Binding is greatly enhanced following tyrosine phosphorylation by insr and probably occurs via the phosphorylated YXXM motifs (By similarity).
Interacts with SOCS7 (By similarity). Interacts (via IRS-type PTB domain) with IGF1R and INSR (via the tyrosine-phosphorylated NPXY motif) (By similarity). Interacts with UBTF, FER and PIK3CA (By similarity). Interacts (via phosphorylated YXXM motifs) with PIK3R1 (PubMed:1380456). Interacts with ROCK1 (PubMed:11739394). Interacts (via PH domain) with PHIP (PubMed:11018022). Interacts with GRB2 (PubMed:8491186). Interacts with ALK (By similarity). Interacts with EIF2AK2/PKR (By similarity). Interacts with GKAP1 (PubMed:25586176). Interacts with DGKZ in the absence of insulin; insulin stimulation decreases this interaction (PubMed:27739494). Found in a ternary complex with DGKZ and PIP5K1A in the absence of insulin stimulation (By similarity).
