Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific; protein heterodimerization activity; and protein homodimerization activity. Involved in retinal bipolar neuron differentiation. Acts upstream of or within negative regulation of macromolecule metabolic process; negative regulation of neuron differentiation; and somatic stem cell population maintenance. Is active in nucleus. Is expressed in brain; liver; and renal vasculature. Orthologous to human ZHX2 (zinc fingers and homeoboxes 2). [provided by Alliance of Genome Resources, Apr 2022]
