The mouse Bright (B-cell regulator of IgH transcription) protein is expressed specifically in B cells and transactivates an IgH enhancer in transient transfection assays. Bright and the Drosophila 'dead ringer' (dri) gene product belong to a protein family whose members share a conserved DNA-binding domain termed the 'A/T-rich interaction domain' (ARID).
