Protein motifs are small regions of protein three-dimensional structure or amino acid sequence shared among different proteins. They are recognizable regions of protein structure that may (or may not) be defined by a unique chemical or biological function.
1. Protein sequence:
Submited protein sequences will be scaned them against the PROSITE collection of motifs. PROSITE motifs encompass both PROSITE profiles and patterns that are used to identify protein domains, families and functional sites. A single file containing all PROSITE motifs can be found at ftp://ftp.expasy.org/databases/prosite/prosite.dat.
