Module 2: Figure Rho-regulated kinases



Structure of Rho GTPase-regulated kinases.

The Rho family exert many of their actions by stimulating protein kinases such as PAK, MRCK and ROCK. These kinases exist as homodimers with PAK being arranged in a head-to-tail manner, whereas MRCK and ROCK have a parallel alignment. The GTP-bound form of these p21 monomeric G proteins bind to a p21-binding domain (PBD). CC, coiled-coil domain: CH, citron homology domain; CRD, cysteine-rich domain; FilGap, filamin GTPase-activating protein; MLCK, myosin light chain kinase; PH, pleckstrin homology domain.
