Kcnq5 Gene Summary [Rat]
Enables voltage-gated monoatomic ion channel activity involved in regulation of presynaptic membrane potential and voltage-gated potassium channel activity. Involved in potassium ion transport. Is active in calyx of Held and presynaptic membrane. Human ortholog(s) of this gene implicated in autosomal dominant intellectual developmental disorder 46. Orthologous to human KCNQ5 (potassium voltage-gated channel subfamily Q member 5). [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 rat Kcnq5 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
