Munc-18

Munc-18 (an acronym for mammalian uncoordinated-18) proteins are the mammalian homologue of UNC-18 (which was first discovered in the nematode worm C. elegans) and are a member of the Sec1/Munc18-like (SM) protein family. Munc-18 proteins have been identified as essential components of the synaptic vesicle fusion protein complex and are crucial for the regulated exocytosis of neurons and neuroendocrine cells.
