Predicted to enable DNA binding activity; IMP dehydrogenase activity; and identical protein binding activity. Involved in response to cold and retina development in camera-type eye. Predicted to be located in cytosol and nucleus. Predicted to be active in cytoplasm. Human ortholog(s) of this gene implicated in Leber congenital amaurosis 11; retinitis pigmentosa; and retinitis pigmentosa 10. Orthologous to human IMPDH1 (inosine monophosphate dehydrogenase 1).
