When I search through a promoter sequence database, like Gene2Promoter and Eukaryotic Promoter Database (EPD), sometimes, I get more sequences with 1 gene ID. How can that be?
It has the fact that each gene ID corresponds to 1 promoter sequence? Or am I wrong? How can it be that 1 gene ID gives more promoter sequences as result? Are those promoter sequences allele sequences of that specific gene ID?
