This is SWISS-MODEL Beta server. Modelling hetero-oligomers is now possible!

You can input multiple target sequences for a single modelling job.
Enter the first sequence the normal way with copy and paste, or add a UniProtKB AC, then add another - and another - and another!

SWISS-MODEL | Terms of Use


SWISS-MODEL generates theoretical models by automated homology modelling techniques. The result of any theoretical modelling procedure is NON-EXPERIMENTAL and must be considered with care as models may contain significant errors. This is especially true for automated modelling since there is no human intervention during model building. All information on the SWISS-MODEL site is provided "AS-IS", without any warranty, expressed or implied. SWISS-MODEL and SWISS-MODEL Repository are developed within the SIB Swiss Institute of Bioinformatics — please visit ExPASy for more details on terms and conditions for SIB services.


SWISS-MODEL is developed by the Computational Structural Biology Group at the SIB Swiss Institute of Bioinformatics at the Biozentrum, University of Basel.
