About Pik3cb

Chromosome 9: 98,918,707-99,022,674 reverse strand.GRCm39:CM001002.3

This gene has 3 transcripts (splice variants), 214 orthologues, 9 paralogues and is associated with 48 phenotypes. Ubiquitous expression in placenta adult (RPKM 11.2), subcutaneous fat pad adult (RPKM 5.) and 28 other tissues.

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, Apr 2022]
