Cntnap1 Gene Summary [Rat]
Enables SH3 domain binding activity. Predicted to be involved in several processes, including myelination; protein localization to axon; and synapse organization. Predicted to act upstream of or within neuron projection development. Located in paranode region of axon. Is active in presynaptic active zone. Human ortholog(s) of this gene implicated in lethal congenital contracture syndrome. Orthologous to human CNTNAP1 (contactin associated protein 1).

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 rat Cntnap1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
