Predicted to enable RNA polymerase II-specific DNA-binding transcription factor binding activity; histone deacetylase binding activity; and transcription coregulator binding activity. Predicted to be involved in negative regulation of transcription by RNA polymerase II and terminal button organization. Predicted to act upstream of or within chromatin organization. Located in nucleus. Part of NuRD complex and protein-DNA complex. Is expressed in several structures, including alimentary system; branchial arch; cardiovascular system; genitourinary system; and nervous system. Orthologous to human CHD4 (chromodomain helicase DNA binding protein 4). [provided by Alliance of Genome Resources, Apr 2022]
