Abstract: The p21-activated kinases (PAKs)， an evolutionarily conserved family of serine/threonine kinases， are expressed in many tissues. As target of the small GTPase of Rho family， PAK can be regulated by many growth factors through GTP-dependent and GTP-independent way. PAKs are important for a variety of cellular functions including cell motility， survival， cell cycle， gene regulation and angiogenesis， especially in tumor invasion and metastasis. In this review， we summarized the current knowledge of PAK with respect to emerging cellular functions and possible contribution to cancer.
