Transcription regulator protein BACH2 is a protein that in humans is encoded by the BACH2 gene.[2][3][4] It contains a BTB/POZ domain at its N-terminus which forms a disulphide-linked dimer [5] and a bZip_Maf domain at the C-terminus.

Model organisms[edit]

Model organisms have been used in the study of BACH2 function. A conditional knockout mouse line called Bach2tm1a(EUCOMM)Wtsi was generated at the Wellcome Trust Sanger Institute.[6] Male and female animals underwent a standardized phenotypic screen[7] to determine the effects of deletion.[8][9][10][11] Additional screens performed: - In-depth immunological phenotyping[12] - in-depth bone and cartilage phenotyping[13]
