Welcome to YeTFaSCo: The Yeast Transcription Factor Specificity Compendium
Latest Version: 1.02

YeTFaSCo is a collection of all available TF specificities for the yeast Saccharomyces cerevisiae in Position Frequency Matrix (PFM) or Position Weight Matrix (PWM) formats. The specificities are evaluated for quality using several metrics. With this website, you can scan sequences with the motifs to find where potential binding sites lie, inspect precomputed genome-wide binding sites, find which TFs have similar motifs to one you have found, and download the collection of motifs.
