| We found that p38alpha can phosphorylate the Rab 5 effectors EEA 1 and Rabenosyn 5 on Thr 1392 and Ser 215 , respectively , and these phosphorylation events regulate the recruitment of EEA 1 and Rabenosyn 5 to membranes . ^^^ Moreover , phosphomimetic mutation of Thr 1392 in EEA 1 can bypass the requirement for p38alpha in MOR endocytosis . ^^^ |
