We find that, although the variant octamer motif binds Oct-1 and Oct-2 in vitro with 5-fold lower affinity than the consensus octamer motif , mutation of the variant octamer motif to either a consensus octamer or non- octamer motif has no effect on transcriptional activation from the germline promoter .
 protein: Oct-2; DNA: non- octamer motif; DNA: germline promoter; DNA: octamer motif; DNA: octamer motif; DNA: consensus octamer motif; DNA: octamer motif; DNA: consensus octamer; protein: Oct-1; DNA: octamer motif
