Details for Dengue NS1 n

Method: Dengue protein is purified by proprietary chromatographic technique. Useful Applications: Each laboratory should determine an optimum working titer for use in its particular application.

Description: The E.coli derived recombinant protein contains the NS1 Dengue Virus n-end Type-2 immunodominant regions. The Recombinant Dengue Virus NS1n is fused to a GST tag. The E.coli derived recombinant protein contains the NS1 Dengue Virus n-end Type-2 immunodominant regions.

Caused by one of four closely related virusserotypesof the genus Flavivirus, family Flaviviridae, each serotype is sufficiently different that there is no cross-protection and epidemics caused by multiple serotypes (hyperendemicity) can occur. In cell culture experiments and mice Morpholinoantisense oligos have shown specific activity against Dengue virus.

Function: Protein C packages viral RNA to form a viral nucleocapsid, and promotes virion budding (By similarity).

Function: prM acts as a chaperone for envelope protein E during intracellular virion assembly by masking and inactivating envelope protein E fusion peptide. prM is matured in the last step of virion assembly, presumably to avoid catastrophic activation of the viral fusion peptide induced by the acidic pH of the trans-Golgi network. After cleavage by host furin, the pr peptide is released in the extracellular medium and small envelope protein M and envelope protein E homodimers are dissociated (By similarity).

Function: Envelope protein E binds cell surface receptor and is involved in membrane fusion between virion and target cell. Synthesized as an homodimer with prM which acts as a chaperone for envelope protein E. After cleavage of prM, envelope protein E dissociate from small envelope protein M and homodimerizes (By similarity).

Function: Non-structural protein 1 is slowly secreted from mammalian cells, but not from mosquito cells. Secreted form elicits protective immune response and plays an essential role in RNA replication. Soluble and membrane-associated NS1 may activate human complement and induce host vascular leakage. This effect might explain the clinical manifestations of dengue hemorrhagic fever and dengue shock syndrome (By similarity).

Subunit: prM and envelope protein E form heterodimers in the endoplasmic reticulum and Golgi. Envelope protein E forms homodimers. NS1 forms homodimers as well as homohexamers when secreted. NS1 may interact with NS4A (By similarity).

Subcellular Location: Protein C: Virion (By similarity).

Subcellular Location: Peptide pr: Secreted (By similarity).

Subcellular Location: Small envelope protein M: Virion membrane; Single-pass type I membrane protein (By similarity).

Subcellular Location: Envelope protein E: Virion membrane; Single-pass type I membrane protein (By similarity).

Subcellular Location: Non-structural protein 1: Secreted. Endoplasmic reticulum membrane; Peripheral membrane protein; Lumenal side (By similarity).

Domain: Transmembrane domains of the small envelope protein M and envelope protein E contains an endoplasmic reticulum retention signals (By similarity).

Ptm: Specific enzymatic cleavages in vivo yield mature proteins. The nascent protein C contains a C-terminal hydrophobic domain that act as a signal sequence for translocation of prM into the lumen of the ER. Mature protein C is cleaved at a site upstream of this hydrophobic domain by NS3. prM is cleaved in post-Golgi vesicles by a host furin, releasing the mature small envelope protein M, and peptide pr (By similarity).

Ptm: Envelope protein E and non-structural protein 1 are N-glycosylated (By similarity).

Miscellaneous: The virion is assembled in the endoplasmic reticulum lumen, transported by vesicles to the Golgi, then transported again to the cell membrane where it is released outside the cell.
