PIK3R1 - phosphoinositide-3-kinase regulatory subunit 1 Gene
Also Known as p85; AGM7; GRB1; IMD36; p85alpha; p85-ALPHA
Species: Homo sapiens
About PIK3R1
This gene has 33 transcripts (splice variants), 248 orthologues, 2 paralogues and is associated with 135 phenotypes. Ubiquitous expression in fat (RPKM 16.6), brain (RPKM 16.6) and 24 other tissues.
Summary
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]
