Turbocharging synaptic transmission
FEBS Letters, 2023 Evidence from biochemistry, genetics, and electron microscopy strongly supports the idea that a ring of Synaptotagmin is central to the clamping and release of synaptic vesicles (SVs) for synchronous neurotransmission. Recent direct measurements in cell‐free systems suggest there are 12 SNAREpins in each ready‐release vesicle, consisting of six ...
