Gene: KCNAB1 (potassium voltage-gated channel subfamily A member regulatory beta subunit 1) Homo sapiens
Symbol: KCNAB1
Name: potassium voltage-gated channel subfamily A member regulatory beta subunit 1
Description: Exhibits NADPH binding activity; potassium channel regulator activity; and protein domain specific binding activity. Involved in negative regulation of voltage-gated potassium channel activity. Localizes to cytosol; extrinsic component of cytoplasmic side of plasma membrane; and voltage-gated potassium channel complex. Implicated in temporal lobe epilepsy.
Type: protein-coding
RefSeq Status: REVIEWED
