Synaptotagmin-1 C2B domain interacts simultaneously with SNAREs and membranes to promote membrane fusion
opi do you sea what i sea Synaptotagmin-1 (Syt1) acts as a Ca2+ sensor for neurotransmitter release through its C2 domains.It has been proposed that Syt1 promotes SNARE-dependent fusion mainly through its C2B domain, but the underlying mechanism is poorly understood.In this study, we show that the C2B domain interacts simultaneously with acidic mem
