The results also revealed a similar functional cooperation between the transcription factors which bind to the Oct and the adjacent Sp 1-binding site in BJA-B cells , as has been observed in HeLa cells , since a template which contains a weak binding site for OTFs expresses wild-type levels of U2 snRNA in both cell types when the weak octamer-binding site is combined with a Sp 1-binding site .
