Summary
Enables 1-phosphatidylinositol-3-kinase activity and insulin receptor substrate binding activity. Involved in several processes, including phosphatidylinositol 3-kinase signaling; regulation of intracellular signal transduction; and response to ischemia. Acts upstream of or within several processes, including angiogenesis involved in wound healing; embryonic cleavage; and homophilic cell adhesion via plasma membrane adhesion molecules. Located in nucleus. Is expressed in several structures, including early embryo; genitourinary system; liver; respiratory system; and spleen. Human ortholog(s) of this gene implicated in glioblastoma; prostate adenocarcinoma; prostate cancer; and type 2 diabetes mellitus. Orthologous to human PIK3CB (phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit beta). [provided by Alliance of Genome Resources, Nov 2021]

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.
