Automated description from the Alliance of Genome Resources (Release 7.4.0)
Predicted to enable A-type (transient outward) potassium channel activity and transmembrane transporter binding activity. 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 cellular response to BMP stimulus; potassium ion transmembrane transport; and regulation of heart rate by cardiac conduction. Located in membrane. Part of voltage-gated potassium channel complex. Is active in GABA-ergic synapse and 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).
