Gene: PIK3R2 (phosphoinositide-3-kinase regulatory subunit 2) Homo sapiens
Analyze
Symbol: PIK3R2
Name: phosphoinositide-3-kinase regulatory subunit 2
Description: Exhibits phosphotyrosine residue binding activity; protein phosphatase binding activity; and receptor tyrosine kinase binding activity. Involved in negative regulation of MAPK cascade; phosphatidylinositol 3-kinase signaling; and regulation of autophagy. Predicted to localize to the nucleus and phosphatidylinositol 3-kinase complex. Implicated in pancreatic ductal adenocarcinoma. Biomarker of colon cancer and prostate cancer.
Type: protein-coding
RefSeq Status: REVIEWED
