To scan DNA sequences for transcription factor binding sites, you provide a DNA sequence and a TF name to retrieve JASPAR PFMs and PWMs, then scan for potential binding sites with scores returned in JSON format. This requires internet access to the JASPAR REST API.

Yes, you can retrieve position frequency matrices from the JASPAR CORE and other collections by searching specifically for transcription factors using TF name, species, or class. Matrix details are returned in JSON format for downstream regulatory genomics workflows.

The best way to convert JASPAR PFMs to PWMs for sequence scanning is to fetch the PFM from the JASPAR REST API and apply the built-in matrix conversion and scanning logic. This returns potential binding sites with scores for your DNA sequences.

Yes, this approach supports regulatory variant interpretation, promoter and enhancer analysis, and gene regulatory network construction. You apply retrieved JASPAR motifs and matrix comparisons directly to these genomics workflows to identify functional regulatory elements.

Yes, you need internet access to query JASPAR transcription factor binding profiles because the skill communicates directly with the JASPAR REST API to fetch PFMs, PWMs, and scan sequences. Without connectivity, matrix retrieval and sequence scanning cannot execute.

A key limitation is that matrix comparisons and sequence scanning depend entirely on the availability and coverage of profiles within the JASPAR collections you query. Results are constrained by the CORE and other specified collections accessed via the REST API.
