This tool provides SIFT predictions for a given protein FASTA sequence by using aligned sequences provided by the user. Your query sequence is the sequence that you would like prediction on (i.e. the sequence in which you have introduced the amino acid substitutions).
The query sequence must be first among the aligned sequences you enter.
Partial sequences should be flanked by Xes at the beginning and end of the sequence so that those positions are not considered gaps (and hence have liberal prediction).
Enter your protein query sequence along with related sequences (not necessarily aligned). These sequences are assumed to be functional, and is what SIFT will base its prediction on. The normal (functional) query sequence should appear first.
