|Gene Description||PIK3R1, phosphoinositide-3-kinase regulatory subunit 1, is the alpha subunit of PI3K that stabilizes and inhibits the catalytic subunit (Pik3ca) until ligand stimulation activates PI3K (PMID: 26807692) for subsequent AKT and mTOR signaling to promote cell growth and survival (PMID: 19629070). PIK3R1 alterations are common in endometrial, glioma, and colon cancers and have also been detected in renal, ovarian, urothelial, breast, and prostate tumors (PMID: 24367658, PMID: 26807692, PMID: 26501081, PMID: 17932254, PMID: 30961830).|
