- _5 value "Transcription of the ornithine decarboxylase (ODC) gene is rapidly elevated by activation of protein kinase A (PKA). The additive influence of three cis-acting elements is responsible for this regulation in an adrenal carcinoma cell line. Two sites, CRE2 at -48 base pairs (bp) relative to the start of transcription and CRE3 at +95 bp, are identical to the core motif of the cAMP-responsive element (CRE) of the somatostatin gene and are conserved in the mouse, rat, and human ODC genes. Mutation of CRE2 resulted in a substantial decrease in basal promoter activity, as well as a 5-fold decrease in inducibility of the ODC promoter by PKA. CRE3 did not contribute to the basal activity of the ODC promoter, but mutation of this site resulted in a 2-fold decrease in inducibility by PKA. Deletion of a 45-bp sequence (GC-box) located 5' of CRE2, also resulted in a 2-fold decrease in inducibility of the ODC promoter. DNase I protection revealed the presence of protein binding at CRE2, the TATA box, and the GC-box of the ODC promoter. Mutation of CRE2 resulted in loss of protection of this sequence, as well as the 3' extension of the footprint over the TATA box, without affecting interactions at the GC box. Antibodies to the well characterized CRE-binding protein CREB recognized proteins binding to CRE2, suggesting that binding of CREB, or an antigenically related protein, is important for the activity of CRE2. Additionally, recombinant CREB bound to a DNA probe containing the CRE2 sequence." provenance.
