Automated description from the Alliance of Genome Resources (Release 3.1.1)
Predicted to contribute to voltage-gated potassium channel activity involved in ventricular cardiac muscle cell action potential repolarization. Predicted to be involved in several processes, including potassium ion transmembrane transport; regulation of heart rate by cardiac conduction; and ventricular cardiac muscle cell membrane repolarization. Localizes to GABA-ergic synapse and integral component of postsynaptic specialization membrane. Is expressed in heart and heart ventricle. Human ortholog(s) of this gene implicated in Brugada syndrome 9 and spinocerebellar ataxia type 19/22. Orthologous to human KCND3 (potassium voltage-gated channel subfamily D member 3).
