Gene: Kcna1 (potassium voltage-gated channel subfamily A member 1) Rattus norvegicus
Symbol: Kcna1
Name: potassium voltage-gated channel subfamily A member 1
Description: Exhibits delayed rectifier potassium channel activity; voltage-gated ion channel activity involved in regulation of postsynaptic membrane potential; and voltage-gated ion channel activity involved in regulation of presynaptic membrane potential. Involved in several processes, including neuronal action potential; neuronal signal transduction; and positive regulation of voltage-gated potassium channel activity. Localizes to several cellular components, including axon; glutamatergic synapse; and integral component of plasma membrane. Used to study episodic ataxia type 1 and visual epilepsy. Human ortholog(s) of this gene implicated in episodic ataxia type 1. Orthologous to human KCNA1 (potassium voltage-gated channel subfamily A member 1); INTERACTS WITH 17alpha-ethynylestradiol; 6-propyl-2-thiouracil; acrylamide.
Type: protein-coding
Also known as: IA; Kcna; Kcpvd; Kv1.1; potassium (K+) channel protein voltage dependent; potassium channel, voltage gated shaker related subfamily A, member 1; potassium voltage gated channel shaker related subfamily member 1; Potassium voltage gated channel, shaker related subfamily, member 1; potassium voltage-gated channel, shaker-related subfamily, member 1; RBKI; RCK1; voltage-gated potassium channel subunit Kv1.1
