Finally, we show that one of the isoforms encodes the previously described lymphoid-specific Oct2B protein which has been suggested to be involved in the function of the octamer motif in the context of the immunoglobulin heavy-chain ( IgH ) enhancer .
 protein: isoforms; DNA: octamer motif; protein: immunoglobulin heavy-chain; DNA: immunoglobulin heavy-chain ( IgH ) enhancer; protein: IgH; protein: lymphoid-specific Oct2B protein
