Jr., Ubol S., Holmes E.C.; RT "The molecular epidemiology of dengue virus serotype 4 in Bangkok, RT Thailand."; RL Virology 329:168-179(2004). CC -!- FUNCTION: Protein C packages viral RNA to form a viral CC nucleocapsid, and promotes virion budding (By similarity). CC -!- FUNCTION: prM acts as a chaperone for envelope protein E during CC intracellular virion assembly by masking and inactivating envelope CC protein E fusion peptide. prM is matured in the last step of CC virion assembly, presumably to avoid catastrophic activation of CC the viral fusion peptide induced by the acidic pH of the trans- CC Golgi network. After cleavage by host furin, the pr peptide is CC released in the extracellular medium and small envelope protein M CC and envelope protein E homodimers are dissociated (By similarity). CC -!- FUNCTION: Envelope protein E binds cell surface receptor and is CC involved in membrane fusion between virion and target cell. CC Synthesized as an homodimer with prM which acts as a chaperone for CC envelope protein E. After cleavage of prM, envelope protein E CC dissociate from small envelope protein M and homodimerizes (By CC similarity). CC -!- FUNCTION: Non-structural protein 1 is slowly secreted from CC mammalian cells, but not from mosquito cells. Secreted form CC elicits protective immune response and plays an essential role in CC RNA replication (By similarity). CC -!- FUNCTION: Non-structural protein 2B is a required cofactor for the CC serine protease function of NS3 (By similarity). CC -!- FUNCTION: Serine protease NS3 displays three enzymatic activities: CC serine protease, NTPase and RNA helicase. NS3 serine protease, in CC association with NS2B, cleaves the polyprotein at dibasic sites in CC the cytoplasm: C-prM, NS2A-NS2B, NS2B-NS3, NS3-NS4A, NS4A-2K and CC NS4B-NS5. NS3 RNA helicase binds RNA and unwinds dsRNA in the 3' CC to 5' direction (By similarity). CC -!- FUNCTION: Non-structural protein 4A plays a role in RNA CC replication. Enhances inhibition of cell antiviral response by CC non-structural protein 4B (By similarity). CC -!- FUNCTION: Non-structural protein 4B prevent the establishment of CC cellular antiviral state by blocking the interferon-alpha/beta CC (IFN-alpha/beta) and IFN-gamma signaling pathways (By similarity). CC -!- FUNCTION: RNA-directed RNA polymerase NS5 replicates the viral (+) CC and (-) genome, and assure the capping of genomes in the CC cytoplasm. May be involved in methylation of 5'RNA cap structure CC (By similarity). CC -!- CATALYTIC ACTIVITY: Selective hydrolysis of -Xaa-Xaa-|-Yaa- bonds CC in which each of the Xaa can be either Arg or Lys and Yaa can be CC either Ser or Ala. CC -!- CATALYTIC ACTIVITY: Nucleoside triphosphate + RNA(n) = diphosphate CC + RNA(n+1). CC -!- CATALYTIC ACTIVITY: S-adenosyl-L-methionine + G(5')pppR-RNA = S- CC adenosyl-L-homocysteine + m(7)G(5')pppR-RNA. CC -!- SUBUNIT: prM and envelope protein E form heterodimers in the CC endoplasmic reticulum and Golgi. Envelope protein E forms CC homodimers. NS1 forms homodimers as well as homohexamers when CC secreted. NS1 may interact with NS4A. NS3 and NS2B form an CC heterodimer. NS3 interacts with unphosphorylated NS5 (By CC similarity). CC -!- SUBCELLULAR LOCATION: Protein C: Virion. Peptide pr: Secreted CC protein. Small envelope protein M: Virion; virion membrane; CC single-pass type I membrane protein. Envelope protein E: Virion; CC virion membrane; single-pass type I membrane protein. Non- CC structural protein 1: Secreted protein. Endoplasmic reticulum; CC endoplasmic reticulum membrane; peripheral membrane protein; CC lumenal side. Non-structural protein 2A-alpha: Endoplasmic CC reticulum; endoplasmic reticulum membrane. Non-structural protein CC 2A: Endoplasmic reticulum; endoplasmic reticulum membrane. Serine CC protease subunit NS2B: Endoplasmic reticulum; endoplasmic CC reticulum membrane; peripheral membrane protein; cytoplasmic side. CC Serine protease subunit NS3: Endoplasmic reticulum; endoplasmic CC reticulum membrane; peripheral membrane protein; cytoplasmic side. CC Non-structural protein 4A: Endoplasmic reticulum; endoplasmic CC reticulum membrane; peripheral membrane protein; cytoplasmic side. CC Non-structural protein 4B: Endoplasmic reticulum; endoplasmic CC reticulum membrane; peripheral membrane protein; cytoplasmic side. CC RNA-directed RNA polymerase NS5: Endoplasmic reticulum; CC cytoplasmic side. Nucleus. Note=The virion is assembled in the CC endoplasmic reticulum lumen, transported by vesicles to the Golgi, CC then transported again to the cell membrane where the virion is CC released outside the cell. The C-terminal transmembrane domains of CC non-structural protein 4B is presumably reoriented after cleavage CC on the cytoplasmic side (By similarity). CC -!- DOMAIN: Transmembrane domains of the small envelope protein M and CC envelope protein E contains an endoplasmic reticulum retention CC signals (By similarity). CC -!- PTM: Specific enzymatic cleavages in vivo yield mature proteins. CC The nascent protein C contains a C-terminal hydrophobic domain CC that act as a signal sequence for translocation of prM into the CC lumen of the ER. Mature protein C is cleaved at a site upstream of CC this hydrophobic domain by NS3. prM is cleaved in post-Golgi CC vesicles by a host furin, releasing the mature small envelope CC protein M, and peptide pr. Non-structural protein 2A-alpha, a C- CC terminally truncated form of non-structural protein 2A, results CC from partial cleavage by NS3 (By similarity). CC -!- PTM: RNA-directed RNA polymerase NS5 is phosphorylated on serines CC residues. This phosphorylation may trigger NS5 nuclear CC localization (By similarity). CC -!- PTM: Envelope protein E and non-structural protein 1 are N- CC glycosylated (By similarity). CC -!- SIMILARITY: Contains 1 helicase ATP-binding domain. CC -!- SIMILARITY: Contains 1 helicase C-terminal domain. CC -!- SIMILARITY: Contains 1 peptidase S7 domain. CC -!- SIMILARITY: Contains 1 RdRp catalytic domain.
