Interaction of dengue virus envelope protein with endoplasmic reticulum-resident chaperones facilitates dengue virus production
Dengue virus infection is an important mosquito-borne disease and a public health problem worldwide. A better understanding of interactions between human cellular host and dengue virus proteins will provide insight into dengue virus replication and cellular pathogenesis. The glycosylated envelope pr...
