Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables delayed rectifier potassium channel activity. Involved in several processes, including cellular response to magnesium ion; detection of mechanical stimulus involved in sensory perception; and nervous system development. Located in several cellular components, including axon; cell surface; and perikaryon. Part of voltage-gated potassium channel complex. Is active in axon initial segment. Is expressed in several structures, including adipose tissue; alimentary system; genitourinary system; immune system; and nervous system. Used to study epilepsy; episodic ataxia type 1; and temporal lobe 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).
