SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

JASPAR provides open-access transcription factor binding profiles; this skill enables researchers to query profiles, generate PWMs, and assess motif occurrences in DNA sequences to support regulatory genomics analyses.

Core Features & Use Cases

  • Search for TF binding profiles by name, species, and class using the JASPAR REST API.
  • Fetch full matrix details, convert PFMs to PWMs, and scan sequences for potential TF binding sites.
  • Use cases include promoter/enhancer analysis, GWAS regulatory variant interpretation, and ChIP-seq/ATAC-seq motif enrichment.

Quick Start

Provide a DNA sequence and a TF name to scan for binding motifs using JASPAR PWMs.

FAQPage Schema
How do I scan DNA sequences for transcription factor binding sites using JASPAR PWMs?

To scan DNA sequences for transcription factor binding sites, provide a DNA sequence and a TF name. The skill fetches profiles from the JASPAR REST API, converts PFMs to PWMs with pseudocounts, and performs strand-aware sequence scanning using a defined threshold to predict TF binding sites.

What is the JASPAR CORE collection used for in regulatory genomics analysis?

The JASPAR CORE collection provides curated, open-access transcription factor binding profiles used as references for regulatory genomics. It supplies the position frequency matrices needed to generate PWMs for predicting TF binding sites during promoter analysis and motif enrichment.

Can I use JASPAR motif scanning to interpret regulatory variants from GWAS data?

Yes, JASPAR motif scanning supports GWAS regulatory variant interpretation. By scanning DNA sequences with JASPAR PWMs, you can assess whether genetic variants alter predicted transcription factor binding sites, helping to identify potential regulatory mechanisms underlying GWAS signals.

How do I search for transcription factor binding profiles by species and TF class?

You can search for transcription factor binding profiles by querying the JASPAR REST API with specific parameters for TF name, species, and class. This retrieves matching profile matrices from the CORE collection, which can then be converted to PWMs for downstream sequence scanning.

Does JASPAR motif scanning work for ChIP-seq and ATAC-seq motif enrichment analysis?

Yes, JASPAR motif scanning works for ChIP-seq and ATAC-seq motif enrichment analysis. You can use the generated PWMs to scan peak or accessible chromatin sequences to identify enriched transcription factor binding motifs, supporting functional interpretation of epigenomic data.

Do I need to apply pseudocounts when converting PFMs to PWMs for TFBS prediction?

Yes, pseudocounts are required when converting position frequency matrices to PWMs for TFBS prediction. The skill applies pseudocounts during PWM generation to avoid zero-probability weights, ensuring strand-aware sequence scanning produces robust transcription factor binding site predictions.
