PIK3R1

Species
Homo sapiens
Symbol
PIK3R1
Name
phosphoinositide-3-kinase regulatory subunit 1
Synonyms
  • AGM7
  • GRB1
Biotype
protein coding gene
Automated Description
Enables several functions, including insulin binding activity; phosphotyrosine residue binding activity; and signaling receptor binding activity. Involved in several processes, including cell surface receptor signaling pathway; positive regulation of macromolecule biosynthetic process; and regulation of signal transduction. Located in cytoplasm. Part of phosphatidylinositol 3-kinase complex, class IA. Implicated in several diseases, including SHORT syndrome; agammaglobulinemia 7; astroblastoma; endometrial cancer (multiple); and immunodeficiency 36. Biomarker of arthritis (multiple); astroblastoma; carcinoma (multiple); colorectal cancer; and prostate cancer.
RGD Description
Phosphatidylinositol 3-kinase phosphorylates the inositol ring of phosphatidylinositol at the 3-prime position. The enzyme comprises a 110 kD catalytic subunit and a regulatory subunit of either 85, 55, or 50 kD. This gene encodes the 85 kD regulatory subunit. Phosphatidylinositol 3-kinase plays an important role in the metabolic actions of insulin, and a mutation in this gene has been associated with insulin resistance. Alternative splicing of this gene results in four transcript variants encoding different isoforms. [provided by RefSeq, Jun 2011]
