This PIK3CA E545K/PIK3R1 (p110 alpha E545K/p85 alpha) recombinant human protein (full length) was expressed in insect cells. PIK3CA (E545K)/PIK3R1 lipid kinase (p110 alpha E545K/p85 alpha) consists 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 PIK3CA catalytic subunit 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 PIK3CA is essential for vascular development and inactivation of PIK3Ca leads to severe defects in angiogenic sprouting and vascular remodeling. PIK3CA E545K/PIK3R1 (p110 alpha E545K/p85 alpha) recombinant human protein is also available in our SelectScreen™ Kinase Profiling Service.
