Transcription regulator that excerts its function by binding to histone deacetylases and transcription factors. Can repress transactivation mediated by TCF12. Homotetramer. Heterotetramer with CBFA2T2 and CBFA2T3. Interacts with TCF12, SIN3A, HDAC1, HDAC2, HDAC3, NCOR1 and NCOR2. Interacts with ATN1 (via its N-terminus); the interaction enhances the transcriptional repression. Most abundantly expressed in brain. Lower levels in lung, heart, testis and ovary. Belongs to the CBFA2T family. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
