Serine/threonine-protein kinase PAK 3 is an enzyme that in humans is encoded by the PAK3 gene.PAK proteins are critical effectors that link Rho GTPases to cytoskeleton reorganization and nuclear signaling. PAK proteins a family of serine/threonine p21-activating kinases serve as targets for the small GTP binding proteins Cdc42 and RAC and have been implicated in a wide range of biological activities.
