Predicted to enable histone deacetylase binding activity; protein kinase binding activity; and transcription corepressor activity. Acts upstream of or within in utero embryonic development. Predicted to be located in nuclear speck. Predicted to be part of protein-containing complex. Predicted to be active in nucleus. Predicted to colocalize with centrosome. Is expressed in genitourinary system and limb ectoderm. Orthologous to human CIR1 (corepressor interacting with RBPJ, CIR1). [provided by Alliance of Genome Resources, Apr 2022]
