These effects of PI 3-kinase were not mediated by previously identified PI 3-kinase effectors , such as protein kinase B , a positive regulator of PI 3-kinase , or the GTPase Rac , and are therefore likely to involve a novel, as yet unknown, effector molecule .
 positive regulator, effector molecule, PI 3-kinase, GTPase, PI 3-kinase effectors, GTPase Rac, protein kinase B, PI 3-kinase, Rac, PI 3-kinase
