Recombinant Human Human PIK3CB, His-tagged

Cat.No.: PIK3R1-31767TH
Product Overview: Recombinant full length Human PIK3CB with N-terminal His tag and recombinant full length Human PIK3R1, untagged, co expressed in a Baculovirus infected Sf9 cell expression system, 124 kDa,and 83kDa respectively.
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.
Conjugation: HIS
