Synaptic vesicle recycling is a highly regulated process that involves the coordinated function of several different presynaptic proteins including the dephosphins, whose dephosphorylation is important for triggering endocytosis. Subsequent rounds of endocytosis then depend on rephosphorylation of dephosphins. Recent work establishes Cdk5 as a dephosphin kinase whose function is necessary for synaptic vesicle endocytosis.
