Directional sensing requires G(beta)(gamma)-mediated PAK1 and PIX(alpha)-dependent activation of Cdc42

Article Abstract:

Research has been conducted on G(beta)(gamma), PAK-associated guanine nucleotide exchange factor (PIX(alpha)), Cdc42 and p21-activated kinase (PAK). The authors describe the signaling mechanism involving G(beta)(gamma), PIX(alpha), Cdc42 and PAK, and they suggest that G(beta)(gamma) binds PAK1 and activates Cdc42 via PAK-associated PIX(alpha), and that in turn Cdc42 activates PAK1.
