RepEnTools

RepEnTools bundles various software with carefully chosen and validated settings to provide a complete solution for genome-wide repeat element enrichment analysis of ChIP-seq and similar chromatin pulldown experiments, from raw input files to tabular and graphical outputs.

Key Features:

• Complete analysis workflow: Processes raw input files through to tabular and graphical outputs for repeat element enrichment analysis.
• Software integration: Bundles various software tools with validated parameter settings for chromatin pulldown experiments.
• Accessibility: Implementations are available through Galaxy and UNIX environments.
• Species applicability: Demonstrated on human UHRF1 Tandem-Tudor domain data and mouse UHRF1 ChIP-seq data.

Scientific Applications:

• Repeat element enrichment analysis: Identifies enrichment of proteins or chromatin marks on repeat elements in ChIP-seq and similar chromatin pulldown experiments.
• UHRF1 Tandem-Tudor domain binding analysis: Discovered enrichment of hUHRF1 TTD binding on young primate and hominid specific polymorphic repeats (SVA, L1PA1/L1HS) overlapping known enhancers and decorated with H3K4me1-K9me2/3 modifications.
• Cross-species conservation studies: Enables comparison of repeat element silencing mechanisms across mammalian species, as demonstrated for human and mouse UHRF1.
• Experimental validation support: Findings can be corroborated with qPCR assays using newly developed primate and hominid specific qPCR assays.
