Promoter sequences are DNA sequences that define where transcription of a gene by RNA polymerase begins. Promoter sequences are typically located directly upstream or at the 5' end of the ...

DNA sequences that regulate expression of the insulin gene are located within a region spanning ~400 bp that flank the transcription start site. This region, the insulin promoter, contains a ...

The chicken insulin promoter contains four possible (three overlapping) nonconsensus sequences in the vicinity of the conserved mammalian CRE site, while the zebrafish has two potential nonconsens ...

Promoters, which start gene transcription, showed a dependence on sequence orientation but were less specific to cell types. Enhancers, which boost gene transcription, were active regardless of ...
