Structure of human cholecystokinin gene and its chromosomal location.


We have determined the entire structure of human cholecystokinin (CCK) gene, which is 7 kb in size and separated into three exons. S1 endonuclease analysis has shown two putative transcription initiation sites that are preceded by 'TATA' equivalent sequences located 39 bp and 35 bp upstream from these sites. The promoter region contains five 'G-C box'-like sequences, which are believed to be sp 1-binding sites. By chromosome sorting in combination with velocity sedimentation and Southern hybridization, the human cck gene was mapped on the short arm of human chromosome 3.
