Sequence requirements for the transcription of the rabbit β-globin genein vivo: -80 region

We have performed a detailed analysis of DNA sequences in the -80 region of the rabbit beta-globin gene that are required for transcription. A variety of rabbit beta-globin gene templates deleted at various sites in the -80 region were linked to an SV40-plasmid recombinant and introduced into HeLa cells; under these conditions the rabbit beta-globin gene is expressed from its own promotor. The results show that the conserved GGCCAATCT sequence is required for efficient transcription in vivo and further identify another sequence in the region from about -81 to -96 which is also required for transcription in vivo.
