SNAPPI-View and SNAPPI-Predict are both currently in development. So that you do not visit this web site and leave (never to return) with the impression that it does not do what you want I have included a list of planned features with the hope that it will mean that you return at a later point. Please email me with specific requirements not contained on the list so that I have feed back on what are the most important features. Viewing multiple structural alignments of domain-domain interactions using Jalview Viewing of the structures of multiple domain-domain interactions superimposed using Astexviewer Searching using GO terms Searching using Interpro regions/domains Searching using Swissprot identifiers and numbering A simple searching method for matching user provided sequences to domains in the database to return possible similar interactions seen in structural data. Protein-protein interaction prediction from user provided sequences based on a graphical model of the interactions observed in structural data.
