Comparative Modeling

Despite the usage of homology modeling in protein structure prediction is nowadays limited by the great advances achieved with machine learning methods, comparative modeling of antibodies and docking to their respective antigens has become a very important technique to drive antibody and vaccine design. The quality of the antibody modeling process is critical for the success of these endeavors. Following recent advances in homology modeling with multiple templates simultaneously, in MeilerLab we proposed a new protocol that use multiple templates over the same antibody regions to improve modeling performance[1]. In particular, the homology modeling platform RosettaCM within the software suite Rosetta outperformed other methods when modeling antibodies with long HCDR3s and few available templates. Of note, in the recent past we used the same platform to develop homology modeling protocols for GPCRs[2].
