The protein encoded by this gene is a transcriptional repressor capable of binding an E-box element either as a;homodimer or as a heterodimer with E2A in vitro. The encoded protein also forms heterodimers with E2A proteins in;vivo. This protein is capable of inhibiting the transactivation capability of E47, an E2A protein, in mammalian cells.;This gene is a downstream target of the B-cell receptor signal transduction pathway.
