Recombinant Human PIK3R1, His-tagged

Cat.No.: PIK3R1-1079H
Product Overview: Recombinant full-length mouse p110alpha and human p85alpha were co-expressed by baculovirus in Sf9 insect cells using an N-terminal His tag on both proteins.
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.?
