Automated description from the Alliance of Genome Resources
Exhibits delayed rectifier potassium channel activity and voltage-gated ion channel activity involved in regulation of presynaptic membrane potential. Involved in potassium ion transmembrane transport; regulation of presynaptic cytosolic calcium ion concentration; and regulation of synaptic vesicle exocytosis. Localizes to the integral component of plasma membrane and parallel fiber to Purkinje cell synapse. Human ortholog(s) of this gene implicated in colorectal adenocarcinoma. Orthologous to human KCNH1 (potassium voltage-gated channel subfamily H member 1).
