Predicted to enable transcription corepressor activity. Predicted to be involved in negative regulation of DNA-templated transcription and regulation of transcription by RNA polymerase II. Predicted to be located in nucleus. Predicted to be part of histone deacetylase complex and transcription regulator complex. Used to study Alzheimer's disease. Is an ortholog of human RCOR1 (REST corepressor 1); RCOR2 (REST corepressor 2); and RCOR3 (REST corepressor 3).
