Enables several functions, including histone deacetylase regulator activity; nuclear receptor binding activity; and transcription corepressor activity. Involved in locomotor rhythm. Acts upstream of or within several processes, including hemopoiesis; regulation of gene expression; and regulation of signal transduction. Located in cytoplasm and nucleus. Part of transcription repressor complex. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; integumental system; and sensory organ. Orthologous to human NCOR1 (nuclear receptor corepressor 1). [provided by Alliance of Genome Resources, Apr 2022]
