Phosphorylation of protein phosphatase 2Czeta by c-Jun NH2-terminal kinase at Ser92 attenuates its phosphatase activity.

abstract：:Evidence is provided for direct protein-protein interactions between protein kinase C (PKC) alpha, betaI, betaII, gamma, delta, epsilon, and zeta and members of the Rho family of small GTPases. Previous investigations, based on the immunoprecipitation approach, have provided evidence consistent with a direct interacti...
