The encoded protein contains broad complex, tramtrack, bric-a-brac/poxvirus and zinc finger (BTB/POZ) domains, which is atypical of CNC-bZip family members. These BTB/POZ domains facilitate protein-protein interactions and formation of homo- and/or hetero-oligomers. When this encoded protein forms a heterodimer with MafK, it functions as a repressor of Maf recognition element (MARE) and transcription is repressed. Multiple alternatively spliced transcript variants have been identified for this gene. [provided by RefSeq, May 2009] Annotation information Note: BACH1 (Gene ID: 571) and BRIP1 (Gene ID: 83990) share the BACH1 symbol/alias in common. BACH1 is a widely used alternative name for BRCA1 interacting protein C-terminal helicase 1 (BRIP1), which can be confused with the official symbol for BTB domain and CNC homolog 1 (BACH1).
