<p>Could you tell me how to find the promoter position of a gene in the chromosome?
Recently I did ATAC-seq expriment and got the result, showing that the peaks related to some genes is assigned to &quot;promoter&quot;. The result gives the chromosome position of the peak but I am curious about whether the promoters of these genes really overlap the peak position. For example, a peak in chromosome 1 (ref genome: mm39; position: 149975557~149975957) is assigned to the gene &quot;Ptgs2&quot;, and the annotation is &quot;Promoter (&lt;=1kb)&quot;. So where can I get the precise coordination of the promoter for &quot;Ptgs2&quot;? I tried UCSC, Ensembl, or NCBI's Genome Data Viewer but cannot find the promoter information of the gene.</p>
<p>Thank you！</p>

Does this help? https://epd.expasy.org/epd/cgi-bin/get_doc?db=mmEpdNew&format=genome&entry=Ptgs2_1 Also, how exactly are you defining the "start" and "end" positions of a promoter? I admit I haven't worked on this sort of thing much, but I believe they're kind of "fuzzy", promoters.

So where can I get the precise coordination of the promoter for "Ptgs2"? I tried UCSC, Ensembl, or NCBI's Genome Data Viewer but cannot find the promoter information of the gene.

Thank you！
