    Summary
    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 CLOVES syndrome and 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). [provided by Alliance of Genome Resources, Dec 2024]

    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.
