Overexpression of either Sp1 or phosphorylated CREB transactivated the mCgA promoter dose dependently , while coexpression of both transcription factors resulted in an additive mCgA promoter response . mCgA - 92 to - 64 bp , comprising the Sp1 / Egr - 1 site and the CRE motif , conferred gastrin responsiveness to a heterologous thymidine kinase promoter system , and therefore functions as a " true " enhancer element .
