Enables identical protein binding activity. Acts upstream of or within negative regulation of smooth muscle cell differentiation; negative regulation of transcription, DNA-templated; and neurogenesis. Located in nucleus. Is expressed in several structures, including arterial system; central nervous system; genitourinary system; heart; and respiratory system. Human ortholog(s) of this gene implicated in patent ductus arteriosus. Orthologous to human PRDM6 (PR/SET domain 6). [provided by Alliance of Genome Resources, Apr 2022]
