Predicted to enable voltage-gated potassium channel activity and voltage-gated sodium channel activity. Involved in cellular response to dopamine and response to cisplatin. Located in several cellular components, including cone cell pedicle; dendrite; and neuronal cell body. Biomarker of Parkinson's disease. Orthologous to human HCN3 (hyperpolarization activated cyclic nucleotide gated potassium channel 3). [provided by Alliance of Genome Resources, Apr 2022]
