Predicted to enable calmodulin binding activity and syntaxin-1 binding activity. Involved in regulation of multicellular organismal process; spermatogenesis; and synaptic vesicle exocytosis. Located in presynaptic active zone. Expressed in head neurons; neurons; tail neurons; and ventral nerve cord. Human ortholog(s) of this gene implicated in amyotrophic lateral sclerosis. Is an ortholog of human UNC13C (
