Recombinant Human Human PIK3CA, His-tagged

• Cat.No.: PIK3R1-29688TH
• Product Overview: Recombinant full length Human PI 3 Kinase p110alpha mutant + PI 3 kinase p85 alpha coexpressed by baculovirus in Sf9 insect cells with N terminal His tag on both proteins. Molecular weights: 111kDa and 86kDa

Specification

• 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
• Biological activity: The specific activity of PI 3 Kinase p110alpha + PI 3 kinase p85 alpha was determined to be 50 nm/min/mg as per activity assay protocol.
