Guanosine Diphosphate 121-124 AKT serine/threonine kinase 1 Homo sapiens 131-134 15649357-6 2005 While the Rac-specific GEF activity of Cool-2 is mediated through the Dbl homology (DH) domain from one monomer and the Pleckstrin homology domain from the other, activated Cdc42 interacts with the DH domain, most likely opposite the DH domain binding site for GDP bound Rac. Guanosine Diphosphate 261-264 AKT serine/threonine kinase 1 Homo sapiens 10-13
