NEUROBIOLOGY Controlling the Synapse

Synapses in the neuromuscular junction are key components involved in control of muscle movement. Kittel et al. (see the Perspective by Atwood) describe the role of Drosophila Bruchpilot (BRP), a coiled-coil domain protein, in the establishment and maintenance of synapses. BRP was localized to donut-shaped structures centered at the transmitter release sites (active zones) of Drosophila neuromuscular synapses. In mutants lacking BRP, presynaptic membranes were defective. The authors suggest that BRP is needed to form a fully functional synapse and might mediate presynaptic changes in vivo by establishing a proximity between Ca2+ channels and vesicles at release sites.
