Using a cDNA probe, genomic clones were obtained for the 5' flanking promoter sequence of the human somatostatin receptor 2-encoding gene (SSTR2). A 3.8-kb sequence directly upstream from the start codon was analyzed. This sequence shares a number of characteristics with the promoters of other G-protein-coupled receptor (GPCR)-encoding genes including a number of G+C-rich regions, binding sites for several transcriptional factors, and the absence of coupled TATAA and CAAT sequences.
