Summary: Enables phosphatidylinositol 3-kinase activator activity; phosphatidylinositol 3-kinase binding activity; and transmembrane receptor protein tyrosine kinase adaptor activity. Involved in several processes, including insulin receptor signaling pathway; positive regulation of B cell proliferation; and positive regulation of cell communication. Acts upstream of or within several processes, including cellular response to insulin stimulus; positive regulation of cell population proliferation; and positive regulation of epithelial cell migration. Located in cytosol and plasma membrane. Is expressed in several structures, including brain ventricular layer; hindlimb digit skin; jaw; metanephros; and thymus primordium. Used to study type 2 diabetes mellitus. Human ortholog(s) of this gene implicated in type 2 diabetes mellitus. Orthologous to human IRS2 (insulin receptor substrate 2).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
