In Silico Perspective into Interactions and Mutations in Human TLR4 and Ebola Glycoprotein
Abstract
Toll-Like Receptor-4 (TLR4) senses life-threatening Ebola virus Glycoprotein (GP) and produces pro-inflammatory cytokines, resulting in lethal Ebola virus infections. GP2-subunit of Ebola promotes viral entry via membrane fusion. The present study models, optimizes and demonstrates the 3D monomer of the responsible human protein. The essential residue (studied from wet-laboratory research) was observed to be functionally conserved from multiple-sequence alignment. Thus, after performing point-mutation, the mutant protein was satisfactorily re-modelled; keeping its functionality preserved. Comparable residual participation in GP2 and each of the proteins was examined, individually. Stability of the proteins and protein-GP2 complexes on mutation; were discerned via energy calculations, solvent-accessibility area and conformational switching, with supportive statistical significances. Therefore, this probe paves a pathway to examine the weaker interaction of the stable mutated human protein with Ebola GP2 protein, thereby defending the Ebola viral entry.
