The MEME Suite web server is a unified portal for discovery and analysis of sequence motifs (e.g. DNA binding sites, protein interaction domains). Motifs with/without gaps may be discovered, searched for in DNA and protein databases, compared to other motifs and analyzed for putative function by association with gene ontology terms.
MEME is a tool designed for discovering and searching for DNA motifs such as transcription factor binding sites (TFBS) or protein domains.
Sequence Harmony detects subfamily specific functional sites from a multiple sequence alignment by scoring compositional differences between given subfamily groupings.
