title: Location matters: synaptotagmin helps place vesicles near calcium channels.
abstract: Positioning releasable vesicles near voltage-gated calcium channels may ensure transmitter release upon calcium influx. Disruption of vesicle positioning may underlie short-term synaptic depression. However, how this positioning is achieved is unclear. In this issue of Neuron, Young and Neher find that synaptotagmin 2 helps to align readily releasable vesicles near calcium channels at nerve terminals.
