Active Recombinant Human PIK3CA/PIK3R1 protein, His-tagged

• Cat.No.: PIK3CA&PIK3R1-154H
• Product Overview: Recombinant full-length human p110 alpha subunit and p85 alpha subunit were co-expressed by baculovirus in Sf9 insect cells using an N-terminal His tag on both proteins.

Specification

• Description: The PI3K comprises of a 110 kDa catalytic subunit and an 85 kDa regulatory subunit. A number of isoforms of the 110 kDa catalytic subunit and the 85 kDa regulatory subunit exist in cells. The p110 alpha catalytic subunit (PIK3CA) is frequently mutated or amplified in a variety of cancers including ovarian and colon and this protein is one of the PI3K mutants. PIK3CA gene copy number is increased in over 30% of ovarian cancers and this leads to increased PI3-kinase activity. Furthermore, the activity of p110 alpha is essential for vascular development and inactivation of p110 alpha leads to severe defects in angiogenic sprouting and vascular remodeling.
