Active Recombinant Full Length Human PIK3CA and PIK3R1 Co-expressed Protein, N-His-tagged

• Cat.No.: PIK3CA-PIK3R1-134HFL
• Product Overview: Complex of N-terminal 6His-tagged recombinant full-length human p110α and untagged, recombinant, full length, human p85α. Coexpressed by baculovirus in Sf21 insect cells. Purified using Ni2+/NTA-agarose.

Specification

• Description: Phosphatidylinositol 3-kinase is composed of an 85 kDa regulatory subunit and a 110 kDa catalytic subunit. The protein encoded by this gene represents the catalytic subunit, which uses ATP to phosphorylate PtdIns, PtdIns4P and PtdIns(4,5)P2. This gene has been found to be oncogenic and has been implicated in cervical cancers.
