RaptorX: a Web Portal for Protein Structure and Function Prediction

This web portal for protein structure and function prediction is developed by Xu group, excelling at secondary, tertiary and contact prediction for protein sequences without close homologs in the Protein Data Bank (PDB). Given a protein sequence, RaptorX predicts its secondary and tertiary structures as well as contact map, solvent accessibility, disordered regions and binding sites. RaptorX assigns confidence scores to indicate the quality of prediction results. RaptorX-Binding predicts the binding sites of a protein sequence, based upon the predicted 3D model by RaptorX. More details can be found HERE.

Currently the following servers are running. Instructions.
RaptorX Structure Prediction: template-based tertiary structure prediction. For only secondary structure prediction, please use RaptorX-Property, which is much faster. This server is ranked 1st in the past 3 months in the fully-automated blind test CAMEO. See here for a ranking list of the publicly-released structure prediction servers.

Instructions:

1. Registration is NOT required, but users are STRONGLY RECOMMEND to provide an email address in submission, which can be used to retrieve the job results. Jobs can be submitted using a web browser or a command-line program curl. Each user, identified by an email address, can have up to 500 sequences pending prediction at any time point. Jobs are NOT first come, first-served, but are scheduled to ensure a fair share of the service. A user has the HIGHEST priority if not being served in the past 2 days. The less served a user is, the higher priority this user has.

2. A job result can be retrieved by the assigned JobID or its sequence or downloaded through My Jobs. The result URL will also be sent to the email address if provided in submission. If you cannot retrieve your jobs results, please contact the RaptorX team by the form.

3. To see the result web page for interactive visualization, your browser shall support HTML5 and allow JavaScript, which is default on most modern browsers such as FireFox, Chrome, IE, Opera and Safari on several platforms (iPAD, Windows and Mac). To speed up your web browsers, consult here.

Top1 In Casp12 Contact Prediction | 2016-12-06 12:36:30

Our RaptorX-Contact was officially ranked 1st in contact prediction in terms of F1 score in the worldwide protein structure prediction (CASP) competition round XII.

System Under Maintenance | 2015-09-30 09:27:50

The computing systems running the servers are under maintenance, so your jobs will be delayed. However, you can still submit new jobs to the servers.

Retrieve Jobs By Their Sequences | 2015-08-12 05:58:42

Sometimes users cannot receive the email notifications upon completion of their jobs due to various reasons. Now users can retrieve jobs by their sequences so that they do not have to keep a record of the job IDs. However, only sequences submitted in the past 60 days can be retrieved since after 60 days it is better to re-predict their sequences, which may result in a better result due to database enlargement.
