BACH2
Transcription regulator protein BACH2 is a protein that in humans is encoded by the BACH2 gene.[5][6][7] It contains a BTB/POZ domain at its N-terminus which forms a disulphide-linked dimer [8] and a bZip_Maf domain at the C-terminus.
Model organisms
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.[9] Male and female animals underwent a standardized phenotypic screen[10] to determine the effects of deletion.[11][12][13][14] Additional screens performed: - In-depth immunological phenotyping[15] - in-depth bone and cartilage phenotyping[16]
