Cntn1 Gene Summary [Mouse]
Enables carbohydrate binding activity. Involved in central nervous system myelin formation and locomotory behavior. Acts upstream of or within several processes, including nervous system development; positive regulation of neuron projection development; and positive regulation of sodium ion transport. Located in myelin sheath. Is active in glutamatergic synapse; postsynaptic membrane; and presynaptic membrane. Is expressed in several structures, including alimentary system; nervous system; respiratory system; sensory organ; and urinary system. Used to study Compton-North congenital myopathy. Human ortholog(s) of this gene implicated in Compton-North congenital myopathy. Orthologous to human CNTN1 (contactin 1). [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 Cntn1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
