Dengue virus capsid protein facilitates genome compaction and packaging
Boon, Priscilla L. S.; Silva Martins, Ana; Lim, Xin Ni; Enguita, Francisco J.; Santos, Nuno C.; Bond, Peter J.; Wan, Yue; Martins, Ivo C.Dengue virus (DENV) is a single-stranded (+)-sense RNA virus that infects humans and mosquitoes, posing a significant health risk in tropical and subtropical regions. Mature virions are composed of an icosahedral shell of envelope (E) and membrane (M) proteins circumscribing a lipid bilayer, which in turn contains a complex of the approximately 11 kb genomic RNA with capsid (C) proteins. Whereas the structure o...
The pseudo-circular genomes of Flaviviruses: structures, mechanisms, and functi...
De Falco, Louis; Silva, Nelly; Santos, Nuno C.; Huber, Roland G.; Martins, Ivo C.The circularization of viral genomes fulfills various functions, from evading host defense mechanisms to promoting specific replication and translation patterns supporting viral proliferation. Here, we describe the genomic structures and associated host factors important for flaviviruses genome circularization and summarize their functional roles. Flaviviruses are relatively small, single-stranded, positive-sen...
Understanding dengue virus capsid protein disordered N‑Terminus and pep14-23-ba...
Faustino, André F.; Guerra, Gabriela M.; Huber, Roland G.; Hollmann, Axel; Domingues, Marco M.; Barbosa, Glauce M.; Enguita, Francisco J.Dengue virus (DENV) infection affects millions of people and is becoming a major global disease for which there is no specific available treatment. pep14-23 is a recently designed peptide, based on a conserved segment of DENV capsid (C) protein. It inhibits the interaction of DENV C with host intracellular lipid droplets (LDs), which is crucial for viral replication. Combining bioinformatics and biophysics, her...
