Probable corepressor protein acting as a component of a complex that represses transcription (Probable). May play a role, as part of a CoREST-like complex, together with the chromobox protein homologs hpl-1 and hpl-2, in the formation of the vulva and in fertility (PubMed:26476455). May be a component of a CoREST-like complex (PubMed:26476455). May interact with chromobox protein homolog hpl-1 (PubMed:26476455). Belongs to the CoREST family.
