Cplx2 Gene Summary [Mouse]

Predicted to enable calcium-dependent protein binding activity and syntaxin-1 binding activity. Involved in positive regulation of synaptic plasticity and regulation of synaptic vesicle fusion to presynaptic active zone membrane. Is active in calyx of Held and glutamatergic synapse. Is expressed in nervous system; retina layer; and skeletal muscle. Used to study schizophrenia. Orthologous to human CPLX2 (complexin 2). [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 Cplx2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
