In genetics, a sequence motif is a nucleotide or amino-acid sequence pattern that is widespread and has, or is conjectured to have, a biological significance. For proteins, a sequence motif is distinguished from a structural motif, a motif formed by the three dimensional arrangement of amino acids, which may not be adjacent.
An example is the N-glycosylation site motif:
- Asn, followed by anything but Pro, followed by either Ser or Thr, followed by anything but Pro
where the three-letter abbreviations are the conventional designations for amino acids (see genetic code).

Famous quotes containing the word sequence:
“It isn’t that you subordinate your ideas to the force of the facts in autobiography but that you construct a sequence of stories to bind up the facts with a persuasive hypothesis that unravels your history’s meaning.”
—Philip Roth (b. 1933)
