"The presence of both SH2 and SH3 domains in Crk proteins is of crucial importance for their function as adaptor molecules. Crk forms complex with Cas, an SH3 domain-containing docking protein which has been shown to be phosphorylated after PDGF-stimulation of cells, and C3G, a nucleotide exchange protein which has been linked to the activation of JNK."^^ . . . . . . .
