Recruiter that couples transcriptional factors to general transcription apparatus and thereby modulates transcription regulation and chromatin formation. Can both act as an activator or a repressor depending on the context. Mediates MBD1-dependent transcriptional repression, probably by recruiting complexes containing SETDB1. The complex formed with MBD1 and SETDB1 represses transcription and probably couples DNA methylation and histone H3 'Lys-9' trimethylation (H3K9me3) activity (By similarity). Interacts with MBD1, SETDB1 and SP1. Probably forms a complex with SETDB1 and MBD1 (By similarity). Expressed in testis. Expressed in early mouse embryo, especially in the embryonic gonad from 11.5 dpc. Continuously expressed from newborn testis to adult. Belongs to the MCAF family.
