CC -!- FUNCTION: Transcriptional regulator that acts as repressor or activator
CC (PubMed:8887638). Binds to Maf recognition elements (MARE)
CC (PubMed:8887638). Plays an important role in coordinating transcription
CC activation and repression by MAFK (PubMed:8887638). Induces apoptosis
CC in response to oxidative stress through repression of the antiapoptotic
CC factor HMOX1 (By similarity). Positively regulates the nuclear import
CC of actin (PubMed:26021350). Is a key regulator of adaptive immunity,
CC crucial for the maintenance of regulatory T-cell function and B-cell
CC maturation (PubMed:28530713). {ECO:0000250|UniProtKB:Q9BYV9,
CC ECO:0000269|PubMed:26021350, ECO:0000269|PubMed:28530713}.
CC -!- SUBUNIT: Homodimer; disulfide-linked (By similarity). Heterodimer of
CC BACH2 and Maf-related transcription factors (PubMed:8887638).
CC {ECO:0000250|UniProtKB:Q9BYV9, ECO:0000269|PubMed:8887638}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:10809773}. Nucleus
CC {ECO:0000255|PROSITE-ProRule:PRU00978, ECO:0000269|PubMed:10809773}.
CC Note=Nucleocytoplasmic shuttling is controlled by phosphorylation.
CC {ECO:0000250|UniProtKB:Q9BYV9}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=1;
CC IsoId=P97303-1; Sequence=Displayed;
CC Name=2;
CC IsoId=P97303-2; Sequence=VSP_047933;
CC -!- TISSUE SPECIFICITY: Detected in brain and spleen.
CC {ECO:0000269|PubMed:8887638}.
CC -!- DEVELOPMENTAL STAGE: In brain, expression is lower in the adult than in
CC the neonate. {ECO:0000269|PubMed:8887638}.
CC -!- PTM: The reversible disulfide bond may provide a mechanism to regulate
CC the activity in oxidative stress responses.
CC {ECO:0000250|UniProtKB:Q9BYV9}.
CC -!- PTM: Phosphorylation at Ser-520 downstream of the PI-3K pathway
CC promotes nuclear export. {ECO:0000250|UniProtKB:Q9BYV9}.
CC -!- SIMILARITY: Belongs to the bZIP family. CNC subfamily. {ECO:0000305}.
