Hello Everyone,

We are happy to announce the release of the JASPAR 2026 tracks for hg38, mm39, danRer11, galGal6, dm6, ce11, ci3, and sacCer3. These tracks represent genome-wide predicted binding sites for transcription factors with binding profiles in the JASPAR CORE collection. JASPAR is a regularly maintained open-access database that stores manually curated transcription factor (TF) binding profiles as position frequency matrices (PFMs).

The JASPAR 2026 update expanded the JASPAR CORE collection by 12% (306 added or upgraded profiles), culminating in a set of 2,633 non-redundant TF binding profiles. Genome sequences were scanned with JASPAR 2026 CORE TF binding profiles for each taxon independently using PWMScan. For more information, see the track description page.

The JASPAR database is a joint effort among several labs (please see the latest JASPAR paper). Binding site predictions and UCSC tracks were computed by the CBGR team at NCMBM using code developed at the Wasserman Lab. We would like to thank Luis Nassar and Gerardo Perez for their efforts on this release.
