Predicted to enable delayed rectifier potassium channel activity. Acts upstream of or within regulation of neurotransmitter secretion. Located in several cellular components, including neuromuscular junction; neuron projection membrane; and neuronal cell body membrane. Is expressed in aortic valve; arch of aorta; brain; descending thoracic aorta; and thoracic aorta. Human ortholog(s) of this gene implicated in spinocerebellar ataxia type 13. Orthologous to human KCNC3 (potassium voltage-gated channel subfamily C member 3). [provided by Alliance of Genome Resources, Apr 2022]
