Recombinant Human PIK3CA/PIK3R1

• Cat.No.: PIK3CA/PIK3R1-641H
• Product Overview: Recombinant human p110α and p85α were coexpressed ininsect cells.Complex of human full length p110a and p85a subunits of phosphatidylinositol 3-kinase.

Specification

• Cat. No.: PIK3CA/PIK3R1-641H
• Description: The PI3K comprises of a 110 kDa catalytic subunit and a 85 kDa regulatory subunit. A number of isoforms of the 110 kDa catalytic subunit and the 85 kDa regulatory subunit exist in cells. The p110α 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 p110α is essential for vascular development and inactivation of p110α leads to severe defects in angiogenic sprouting and vascular remodeling.
