Active Recombinant Human PIK3CA/PIK3R3 protein, His-tagged

• Cat.No.: PIK3CA&PIK3R3-152H
• Product Overview: Recombinant full-length human PI3K (p110 alpha/p55 gamma) was co-expressed by baculovirus in Sf9 insect cells using an N-terminal His tag.

Specification

• Description: PI3K (p110 alpha/p55 gamma) or Phosphatidylinositol 3-kinase is a lipid kinase that phosphorylates the inositol ring of phosphatidylinositol at the 3-prime position which serve as second messengers in growth signaling pathways. PI3K comprises a 110 kD catalytic subunit and a regulatory subunit of either 85, 55, or 50 kD. Phosphatidylinositol 3-kinase plays an important role in the metabolic actions of insulin, and a mutation in the PI3K has been associated with insulin resistance and plays an important role in glucose homeostasis in vivo. PI3K also plays an essential role in the development and induction of mast cells in normal and pathogenic immune responses.
