What is L1MethDB ?

L1MethDB provides a comprehensive resource and web interface to explore the genomic location and the DNA methylation status of human full-length LINE-1 elements (L1) at single-locus, single-molecule and single-nucleotide resolutions obtained from bs-ATLAS-seq experiments.
...
Bs-ATLAS-seq provides both the location of L1 insertions and their methylation state. Cell lines included in L1MethDB are described below:
