Summary: Enables several functions, including 1-phosphatidylinositol-3-kinase regulator activity; calmodulin binding activity; and enzyme binding activity. Contributes to 1-phosphatidylinositol-3-kinase activity. Involved in several processes, including cell surface receptor protein tyrosine kinase signaling pathway; regulation of protein metabolic process; and response to dexamethasone. Part of phosphatidylinositol 3-kinase complex. Used to study hypertension and portal hypertension. Biomarker of hepatocellular carcinoma; hypertension; obesity; and type 2 diabetes mellitus. Human ortholog(s) of this gene implicated in several diseases, including SHORT syndrome; agammaglobulinemia 7; astroblastoma; endometrial cancer (multiple); and immunodeficiency 36. Orthologous to human PIK3R1 (phosphoinositide-3-kinase regulatory subunit 1). [provided by Alliance of Genome Resources, Dec 2024]
Expression: Biased expression in Thymus (RPKM 301.4), Lung (RPKM 250.0) and 9 other tissues See more

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.
