Background: Non-structural protein 5 (NS5) is considered as an important protein in Dengue viruses (DENVs). It contains N-terminal methyltransferase (MTase) and C-terminal RNA-dependent RNA polymerase (RdRp) domains. NS5 plays a crucial role in the replication of Dengue viruses. Therefore it is considered as an attractive candidate for the development of therapeutics in anti-viral infections and diseases. Aim: The aim of proposed in-silico study was to to screen and identify potential lead molecules with drug like properties to inhibit the activity of NS5 protein in Dengue virus infections. Materials and Methods: Computational bioinformatics analysis was implemented to identify the lead molecules with inhibition activity against MTase and RdRp domains of Dengue virus protein NS5. Phytochemicals and active bioassay compounds were screened based on their reported antiviral mactivities. A total of fifty-one natural compounds and one hundred active compounds were selected by evaluating eighty one bioassay studies. Results: Results of the current study revealed galactomannan, galactan, hyperside, carrageenan, tetrahydroxy, lamdacarragenon, zosteric acid, trihydroxy, quercetin and sulfoximine as top inhibitors of the Dengue virus NS5 protein. Lead molecules namely lamdacarragenon, carrageenan, balsacanea, galactan, trihydroxy, hyperside, myricetin, glycyrrhiza, isosilandrin, rhodiola and silyhermin showed the utmost hydrogen bonding. Overall, we observed that the bioassay active compounds showed less interaction with the MTase and RdRp domains of NS5 protein as compared to natural ligands. Conclusion: Based on the findings of current study, we concluded that the phytochemicals are the most favourable among the docked molecules that showed a significant inhibitory activity against the MTase and RdRp domains of NS5 protein of dengue viruses. We suggest that these lead molecules can be validated experimentally and implemented for the development of therapeutics in viral infections like Dengue.

Epidermal growth factor receptor (EGFR) binds to EGF activating tyrosine phosphorylation through receptor dimerization prompting uncontrolled multiplication. Domain organization, secondary structure combinations in motifs and interactome define such transitory changes responsible for the multi-functionality of human EGFR. We report the predicted phosphorylation sites on Ser, Thr and Tyr residues in addition to 74 auto-phosphorylation sites on Tyr in human EGFR. These data suggest a complex interplay between phosphorylation types for modification resulting in the modulation of human EGFR functionality. It is of further interest in future to thoroughly understand the associated data to clarify the various roles played by post translational modifications (PTM) in human EGFR.
