WebDec 24, 2024 · The promoter region is immediately upstream of the coding sequence. This region can be short (only a few nucleotides in length) or quite long (hundreds of nucleotides long). The longer the promoter, the more available space for proteins to bind. This also adds more control to the transcription process. WebJan 9, 2012 · The first and most studied example of gene regulation by an enhancer is provided by the β-globin locus; here, the locus control region (LCR) is located 40 to 60 kb upstream from the promoter it regulates. The two interact when the chromatin fibre forms new, or rearranges preexisting, loops [ 17, 25 ].

Promoter genetics Britannica
As promoters are typically immediately adjacent to the gene in question, positions in the promoter are designated relative to the transcriptional start site, where transcription of DNA begins for a particular gene (i.e., positions upstream are negative numbers counting back from -1, for example -100 is a position 100 base pairs upstream). WebNov 5, 2024 · A promoter is a short region of DNA (100–1,000 bp) where transcription of a gene by RNA polymerase begins.
