Target Information
Three isoforms of serine/threonine kinases, designated alphaPAK p68, betaPAK p65, and gammaPAK p62, exhibit a high degree of sequence homology with the S. cerevisiae kinase Ste20, involved in pheromone signaling. The alpha, beta, and gammaPAK isoforms complex specifically with Rac1 and Cdc42 in their active GTP-bound state, inhibiting their intrinsic GTPase activity and leading to autophosphorylation. There are eight sites of autophosphorylation on gammaPAK, including Ser19, Ser141, and Thr402, and phosphorylation of Ser141 and Thr402 correlates with gammaPAK activation. Once phosphorylated and their affinity for Rac/Cdc42 reduced, the PAK isoforms dissociate from the complex to seek downstream substrates.
