tokens: To determine whether enhancer elements in addition to the highly conserved octamer ( OCTA ) -nucleotide motif are important for lymphoid-specific expression of the immunoglobulin heavy-chain ( IgH ) gene , we have investigated the effect of mutating the binding site for a putative additional lymphoid-specific transcription factor , designated NF-microB , in the murine IgH enhancer .
