Unc13a Gene Summary [Mouse]
Enables calmodulin binding activity and diacylglycerol binding activity. Involved in several processes, including positive regulation of glutamate receptor signaling pathway; positive regulation of synaptic plasticity; and regulated exocytosis. Acts upstream of or within several processes, including chemical synaptic transmission; modulation of chemical synaptic transmission; and synaptic vesicle maturation. Located in axon; neuromuscular junction; and presynapse. Is active in calyx of Held; glutamatergic synapse; and presynaptic active zone. Is expressed in nervous system and neural retina. Human ortholog(s) of this gene implicated in amyotrophic lateral sclerosis. Orthologous to human UNC13A (unc-13 homolog A). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Unc13a often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
