Enables transcription corepressor activity. Predicted to be involved in several processes, including negative regulation of G1/S transition of mitotic cell cycle; positive regulation of histone acetylation; and regulation of transcription, DNA-templated. Predicted to act upstream of or within Wnt signaling pathway. Located in nucleus. Is expressed in several structures, including central nervous system; genitourinary system; lung; retina; and tooth. Human ortholog(s) of this gene implicated in acute myeloid leukemia. Orthologous to human BRD7 (bromodomain containing 7). [provided by Alliance of Genome Resources, Apr 2022]
