- Motifs are narrowly defined as short, highly conserved regions within domains.
- Motifs are considered required, but not sufficient, components of functional
sites within a biological sequence.
- Motifs are found in sites of post translational modifications, catalytic
or enzymatic activity and binding.
- Motifs within domains have included stretches of amino acids as short as
three residues RGD-cell adhesion to longer "regular expressions" that contain a pattern of usage although specific residues may vary.
- Motifs are derived from multiple sequence alignments.
