Aim.This study aims to model the mutant structures of PSEN2 protein associated with Alzheimer’s disease by comparative modeling using computational tools. Materials and Methods.In the present study, we have retrieved the sequence of the protein from UniProt and a list of mutations that were predicted to have deleterious effects on PSEN2 protein from Alzforum database and performed modeling of the mutant structures using Phyre 2 , Swiss Model and trRosetta Results.Ten mutant structures were modeled by Comparative modeling, threading and ab-initio methods using three web servers.Conclusion.Thus, we have modeled the mutant structures by inducing each of these mutations G212V, I149T, L143H, L238P , P436L, R163C, R284G, S175C, S175F and T430M in the PSEN2 protein using three different molecular modeling web tools used in our study.These mutant structures can further be focused upon for characterization and molecular docking studies in order to find a potential cure for EOAD.
