There is an increasing requirement for the tools to identify of putative mammalian orthologs to enhancers in species other than human and mouse, such as zebrafish, which is lacking whole genome comparison analysis data. Take zebrafish as an example, there are two major methods to identify the orthologs to enhancers in human and mouse,
use the whole genome comparison analysis data and conservation data1,
use spotted gar genome as bridge genome to search the orthologs2.
Both methods will work well in the coding region. However, there is lacking comparative data in distal regulation region such as enhancers and silencers.
In 2020, Emily S. Wong et. al. provides a new method for identification of putative human orthologs to enhancers of zebrafish3. They used the method to interrogate conserved syntenic regions and human and mouse using candidate sponge enhancer sequences. First, they looked for overlap with available functional genomics information. For example, they used mouse ENCODE data to infer enhancer activity based on histone marks in specific tissues. Second, they select the best-aligned region by whole genome alignment from the candidates regions for human and mouse as orthologs. This method provides the possibility to search orthologs for enhancers or silencers even there is not genome comparative data available.
This package is modified from Wong’s methods and provide the easy-to-use script for researchers to quick search putative mammalian orthologs to enhancers. The modified algorithm is: The candidate regions were determined by ENCODE histone marks (default is H3K4me1) in specific tissue for human and mouse. The mapping score were calculated by pairwise Transcription Factors Binding Pattern Similarity (TFBPS) between enhancer sequences and candidates by fast motif match4. The Z-score were calculated from mapping score and then converted to P-value based on two-side test from a normal distribution. The candidates were filtered by p-value and distance from the TSS of target homologs. And then the top candidates from human and mouse were aligned to each other and exported as multiple alignments with given enhancer.
First install enhancerHomologSearch and other packages
required to run the examples. Please note the example dataset used here
is from zebrafish. To run analysis with dataset from a different species
or different assembly, please install the corresponding Bsgenome and
TxDb. For example, to analyze cattle data aligned to bosTau9, please
install BSgenome.Btaurus.UCSC.bosTau9, and
TxDb.Btaurus.UCSC.bosTau9.refGene. You can also generate a TxDb object
by functions makeTxDbFromGFF from a local gff file, or makeTxDbFromUCSC,
makeTxDbFromBiomart, and makeTxDbFromEnsembl, from online resources in
GenomicFeatures package.

markers by markers parameter in the function
getENCODEdata. To make sure the markers are tissue
specific, we can filter the data by biosample_name and
biosample_type parameters. For additional filters, please

enhancer and candidate enhancers via the function
alignmentOne. However, most of the enhancer evolution are
rapid. This package is modified from Wong’s methods and calculate the
alignment score by pairwise Transcription Factors Binding Pattern
Similarity (TFBPS) between enhancer sequences and candidates. This step
is time consuming step. For quick run, users can subset the data by
given genomic coordinates.
