Schematic of synaptic active zone marked by Brp and the voltage-gated calcium channel cacophony (Cac). In EM, cytoplasmic Brp protein localizes to a presynaptic T-bar structure associated with the presynaptic membrane (see K) and as a donut by STED and LLSM when immunostained for the Brp-directed antibody nc82.
