Pik3ca/pik3r1 (human) recombinant protein 20 µg

Phosphatidylinositol 3-kinase phosphorylates the inositol ring of phosphatidylinositol at the 3-prime position. The enzyme comprises a 110 kD catalytic subunités and a regulatory subunités of either 85, 55, or 50 kD. This gene encodes the 85 kD regulatory subunités. 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]
