STRUCTURAL BASIS FOR A MUNC13-1 HOMODIMER- MUNC13-1- RIM HETERODIMER SWITCH: C2-DOMAINS AS VERSATILE PROTEIN-PROTEIN INTERACTION MODULES

Overview

C(2) domains are well characterized as Ca(2+)/phospholipid-binding, modules, but little is known about how they mediate protein-protein, interactions. In neurons, a Munc13-1 C(2)A-domain/RIM zinc-finger domain, (ZF) heterodimer couples synaptic vesicle priming to presynaptic, plasticity. We now show that the Munc13-1 C(2)A domain homodimerizes, and, that homodimerization competes with Munc13-1/RIM heterodimerization. X-ray, diffraction studies guided by nuclear magnetic resonance (NMR) experiments, reveal the crystal structures of the Munc13-1 C(2)A-domain homodimer and, the Munc13-1 C(2)A-domain/RIM ZF heterodimer at 1.44 A and 1.78 A, resolution, respectively. The C(2)A domain adopts a beta-sandwich, structure with a four-stranded concave side that mediates, homodimerization, leading to ... [(full description)]
