This document provides an introduction of the ELMER.data, which contains supporting data for ELMER (Yao, L., Shen, H., Laird, P. W., Farnham, P. J., & Berman, B. P. 2015). ELMER is package using DNA methylation to identify enhancers, and correlates enhancer state with expression of nearby genes to identify one or more transcriptional targets. Transcription factor (TF) binding site analysis of enhancers is coupled with expression analysis of all TFs to infer upstream regulators. ELMER.data provide 3 necessary data for ELMER analysis:

as.data.frame(EPIC.hg38.manifest)[1:5,] %>% datatable(options = list(scrollX = TRUE,pageLength = 5)) ELMER uses the TFClass (Wingender, E., Schoeps, T., Haubrock, M., & Dönitz, J 2014), a classification of eukaryotic transcription factors based on the characteristics of their DNA-binding domains, to identify which are the TF that might be binding to the same region. For example, if a FOXA1 motif is found in a region, there is FOXA2 would also be able to bind to that region. For that ELMER uses two classifications, Family and sub-family. TFClass schema is shown below.
TFClass schema is below:
| Level | Rank denomination | Definition | Example |
|---|---|---|---|
| 1 | Superclass | General topology of the DNA-binding domain | Zinc-coordinating DNA-binding domains (Superclass 2) |
| 2 | Class | Structural blueprint of the DNA-binding domain | Nuclear receptors with C4 zinc fingers (Class 2.1) |
| 3 | Family | Sequence & functional similarity | Thyroid hormone receptor-related factors (NR1) (Family 2.1.2) |
| 4 | Subfamily | Sequence-based subgroupings | Retinoic acid receptors (NR1B) (Subfamily 2.1.2.1) |
| 5 | Genus | Transcription factor gene | RAR-α (Genus 2.1.2.1.1) |
| 4 | Species | TF polypeptide | RAR-α1 (Species 2.1.2.1.1.1) |

HOMER (Heinz, Sven and Benner, Christopher and Spann, Nathanael and Bertolino, Eric and Lin, Yin C and Laslo, Peter and Cheng, Jason X and Murre, Cornelis and Singh, Harinder and Glass, Christopher K 2010) was used with a p-value < 0.0001 to scan a \(\pm 250bp\) region around each probe on HM450K/EPIC using HOCOMOCO V11 motif position weight matrices (PWMs) which provides transcription factor (TF) binding models for more than 600 human TFs. This data set is used in get.enriched.motif function in ELMER to calculate Odds Ratio of motif enrichments for a given set of probes. This data is storaged in a sparse matrix with wuth 640 columns, there is one matrix for HM450K aligned to hg19, one for HM450K aligned to hg38, one for EPIC aligned to hg19, one for EPIC aligned to hg38. Each row is each probe regions (annotation of the regions used can be found in this repository) and each column is motif from http://hocomoco.autosome.ru/ (Kulakovskiy, Ivan V and Medvedeva, Yulia A and Schaefer, Ulf and Kasianov, Artem S and Vorontsov, Ilya E and Bajic, Vladimir B and Makeev, Vsevolod 2013). The value 1 indicates the occurrence of a motif in a particular probe and 0 means no occurrence.
