The novel coronavirus disease (COVID-19) pandemic has emerged in late 2019 and rapidly spread all over the world. In order to assist structure-based discovery efforts for repurposing drugs against the infectious disease, we constructed homology models of SARS-CoV-2 proteins. We identified several potential drugs by comparing the ligand molecules in the template structures with approved or experimental drugs and compounds of natural drugs, including carfilzomib, sinefungin, tecadenoson, and trabodenoson, that would be further investigated for their potential for treating COVID-19.

Protein-protein interactions are fundamental for all biological phenomena. The hub proteins interacting with a number of partner proteins play the vital role in the protein-protein interaction network. We investigated the subcellular localization of proteins in the network, and found that the proteins localized in the multiple subcellular compartments, especially the nucleus and cytoplasm, tend to be hub proteins. Examination on keywords associated with the proteins suggested that those related to post-translational modifications (PTMs) and transcriptions contributed to numerous interactions. Triggered by PTMs in the intrinsically disordered regions, they change interaction partners in the protein complex, and are translocated from cytoplasm to nucleus.
