PIK3R1
-
Official Full Name
phosphoinositide-3-kinase, regulatory subunit 1 (alpha)
-
Overview
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. -
