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 .
