Abstract

Two kilobase segments of the 5'-untranslated regions of the human and rabbit butyrylcholinesterase (BCHE) genes were characterized. The sequences shared extensive identity except for a 333-base pair (bp) Alu repeat present only in human BCHE. One single transcription start site was found in both genes with the techniques of primer extension, amplification of the 5'-end of mRNA, and RNase protection. Cap sites in human and rabbit BCHE genes were found in strictly homologous positions. In human BCHE, the transcription start site was found 157 bp upstream of Met-28, the translation start site. Potential regulatory elements in both promoters included one AP1 site and multiple sites for topoisomerase, Oct-1 and PEA-3. Transient expression of BCHE-reporter gene constructs showed that a 194-bp fragment of the 5'- flanking region of human BCHE and a 570-bp fragment of rabbit BCHE were sufficient for promoting chloramphenicol acetyltransferase activity in HeLa cells. No consensus TATA and CAAT boxes were found. However, the sequence around the transcription start site exhibited homology with initiator elements found in other TATA-less promoters in developmentally regulated genes.
