MethylomeDB: The Brain Methylome Database! This database includes genome-wide DNA methylation profiles for human and mouse brains. DiseaseMeth: A web based resource focused on the aberrant methylomes of human diseases. NGSmethDB: A dedicated database for the storage, browsing and data mining of whole-genome, single-base-pair resolution methylomes. We collect NGS data from high-throughput sequencing together with bisulfite conversion of DNA from literature and public repositories, then generating high-quality chromosome methylation maps for many different tissues, pathological conditions and species. MethBase: A central reference methylome database created from public BS-seq datasets. It contains hundreds of methylomes from well studied organisms. For each methylome, Methbase provides methylation level at individual sites, hypo- or hyper-methylated regions, partially methylated regions, allele-specifically methylated regions, and detailed meta data and summary statistics.

Hi, John

I get used to extract these regions according to the following steps:

1-Download your methylation file;

2-The UCSC Table Browser is a straightforward way to get promoters bases on TSS:

3- Perform the intersection of the two files using "Bedtools intersect"

Hello,

Eukaryotic promoter database may be helpful to you.
