Dengue virus envelope protein and non-structural protein 1 (E protein and NS1 protein)

Dengue virus envelope protein (E protein) is the major surface glycoprotein of the dengue virion and mediates viral attachment and fusion with host cell membranes. The mature dengue virion is decorated with 180 copies of the E protein, organized into head-to-tail homodimers that enable receptor binding and membrane fusion crucial for cell entry[3]. E protein is the main target of neutralizing antibodies and a key determinant of host range. Dengue virus non-structural protein 1 (NS1) is a glycoprotein involved in viral RNA replication, viral assembly, and immune evasion. NS1 exists as a monomer, dimer, or multimer in various cellular compartments and is secreted into the bloodstream during infection. In addition to its role in the viral lifecycle, secreted NS1 protein contributes to dengue pathogenesis by disrupting endothelial integrity, activating complement, and inducing proinflammatory cytokines[1][2][3]. Both E and NS1 proteins are actively explored as antiviral and vaccine targets, and NS1 is a diagnostics biomarker for detecting acute dengue infection. Note: The original target combines two molecular species ("Envelope protein and Nonstructural protein 1"), each with distinct structure and function. For structured analysis or drug discovery, it is preferable to treat them as *separate targets*. This entry merges them as requested, but such grouping is unconventional and may limit interpretability for automated extraction or systematic target annotation.
