Identification of a motif in the carboxyl terminus of beta -arrestin2 responsible for activation of JNK3.


Accumulating evidence indicates that the beta-arrestins act as scaffold molecules that couple G-protein-coupled receptors to mitogen-activated protein (MAP) kinase signaling pathways. Recently, we identified the c-Jun N-terminal kinase 3 (JNK3) as a beta-arrestin2-interacting protein in yeast-two hybrid and co-immunoprecipitation studies. Beta-arrestin2… (More)
