Summary: Enables 1-phosphatidylinositol-3-kinase activity. Involved in several processes, including positive regulation of smooth muscle cell proliferation; response to L-leucine; and response to dexamethasone. Part of phosphatidylinositol 3-kinase complex. Biomarker of autosomal recessive polycystic kidney disease and hepatocellular carcinoma. 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.
