Enables chromatin binding activity; transcription cis-regulatory region binding activity; and transcription corepressor activity. Involved in positive regulation of transcription by RNA polymerase II and protein stabilization. Acts upstream of or within several processes, including fat cell differentiation; regulation of transcription, DNA-templated; and response to estrogen. Part of transcription regulator complex. Is expressed in cerebral cortex ventricular layer and genitourinary system. Human ortholog(s) of this gene implicated in Y-linked deafness 2 and congenital nongoitrous hypothyroidism 8. Orthologous to several human genes including TBL1X (transducin beta like 1 X-linked). [provided by Alliance of Genome Resources, Apr 2022]
