JASPAR

JASPAR is an open access and widely used database of manually curated, non-redundant transcription factor (TF) binding profiles stored as position frequency matrices (PFM) and transcription factor flexible models (TFFM) for TFs from species in six taxonomic groups. From the supplied PFMs, users may generate position-specific weight matrices (PWM). The JASPAR database was introduced in 2004. There were seven major updates and new releases in 2006, 2008, 2010, 2014, 2016, 2018, 2020 and 2022, which is the latest release of JASPAR.

Availability
The JASPAR database is an open-source and freely available for scientific community at http://jaspar.genereg.net/.
