Automated description from the Alliance of Genome Resources (Release 7.1.0)
Enables 1-phosphatidylinositol-3-kinase activity; insulin receptor substrate binding activity; and protein kinase activator activity. Involved in several processes, including cell surface receptor protein tyrosine kinase signaling pathway; cellular response to hydrostatic pressure; and phosphatidylinositol 3-kinase/protein kinase B signal transduction. Acts upstream of with a negative effect on autosome genomic imprinting. Acts upstream of or within several processes, including adipose tissue development; cellular response to glucose stimulus; and negative regulation of apoptotic process. Located in intercalated disc and lamellipodium. Part of phosphatidylinositol 3-kinase complex. Is expressed in several structures, including early embryo; eye; and nervous system. Used to study breast cancer. Human ortholog(s) of this gene implicated in several diseases, including CLOVES syndrome; Cowden syndrome 5; breast cancer (multiple); cutaneous Paget's disease; and gastrointestinal system cancer (multiple). Orthologous to human PIK3CA (phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha).
