BIOINFORMATICS
Promoter Seqeunce Identification
The team isolated regions of approximately 1kbp where the gene promoter was likely to be found. These were compared with commercial promoters (if available) and European Promoter database (EPD). The promoter sequences that appeared on the EPD site have been experimentally analysed, and also did not contain any illegal sites. Thus they were selected, in case of ADH1A1 and ALDH3A1. ALDH1A3 identified by the team had no illegal site, so it was maintained. However, ALDH2 promoter sequence on the EPD site was too small to be included. Therefore a commercial promoter of ALDH2 was selected.
The following gives an example of how a promoter sequences were identified by the iSTEM team:
ALDH1A1
Directionality:5-3
TAATAA= TATA box
GCTGCATACetc = the 5’UTR region.
The promoter includes elements of the 5’UTR plus the grey sequence upstream of it, up to and including the yellow region coding for the forward primer (about 1,000bp in total).
