EndocytoticroleofNDK,PhosphinsandDynamin
Reliable neurotransmitter release requires the presence of sufficent numbers of synaptic vesicles. The process of synaptic vesicle endocytosis (SVE) is coordinated by a group of proteins called dephosphins. The current set of seven known dephosphins are nerve treminal proteins with little or no structural hoimology but satisfy two essential criteria: they are essential for SVE and they are rapidly and coordinately de......阅读全文
