Predicted to enable identical protein binding activity. Acts upstream of or within negative regulation of neuroblast proliferation; negative regulation of smoothened signaling pathway; and positive regulation of neuron differentiation. Located in cytoplasm. Is expressed in several structures, including 1st branchial arch; central nervous system; ectoplacental cone; primitive streak; and sensory organ. Orthologous to human KCTD11 (potassium channel tetramerization domain containing 11). [provided by Alliance of Genome Resources, Apr 2022]
