Entrez gene ID | | 5295 |
Official gene symbol | | PIK3R1 |
Full name | | phosphoinositide-3-kinase, regulatory subunit 1 (alpha) |
Aliases | | ,GRB1,p85,p85-ALPHA, |
Gene 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 three transcript variants encoding different isoforms. [provided by RefSeq] |
