Kcnab1 Gene Summary [Mouse]
Predicted to enable several functions, including NADPH binding activity; potassium channel regulator activity; and transmembrane transporter binding activity. Acts upstream of or within learning or memory and regulation of potassium ion transmembrane transporter activity. Predicted to be located in several cellular components, including cytoplasmic side of plasma membrane; dendrite; and perikaryon. Predicted to be part of voltage-gated potassium channel complex. Predicted to be active in juxtaparanode region of axon. Is expressed in brain; heart; reproductive system; and urinary system. Human ortholog(s) of this gene implicated in temporal lobe epilepsy. Orthologous to human KCNAB1 (potassium voltage-gated channel subfamily A regulatory beta subunit 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 Kcnab1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
