Category:ECO:0005505 ! regular expression motif search evidence

name: regular expression motif search evidence
def: "A type of motif similarity evidence where the motif, a local alignment of sequences, is represented by a regular expression, which captures the variability of nucleotides at each position in a discrete form and can then be used to search genetic sequences by identifying matches to the regular expression." [ECO:SW, PMID:17337630]

comment: Regular expression is a computational tool used for determining whether a given genome contains a DNA region resembling a transcription factor binding motif. For example A/T=W indicates A or T may be present in a column of the alignment. (PMID: 20708667).
