Hantavirus nucleocapsid protein oligomerization.

Oligomerization of hantavirus nucleocapsid protein: analysis of the N-terminal coiled-coil domain.

Hantaviruses constitute a genus in the family Bunyaviridae. They are enveloped negative-strand RNA viruses with a tripartite genome encoding the nucleocapsid (N) protein, the two surface glycoproteins Gn and Gc, and an RNA-dependent RNA polymerase. The N protein is the most abundant component of the virion; it encapsidates genomic RNA segments forming ribonucleoproteins and participates in geno...

N-Terminal Coiled-Coil Domain Nucleocapsid Protein: Analysis of the Oligomerization of Hantavirus

Oligomerization of Hantavirus N protein: C-terminal alpha-helices interact to form a shared hydrophobic space.

The structure of the nucleocapsid protein of bunyaviruses has not been defined. Earlier we have shown that Tula hantavirus N protein oligomerization is dependent on the C-terminal domains. Of them, the helix-loop-helix motif was found to be an essential structure. Computer modeling predicted that oligomerization occurs via helix protrusions, and the shared hydrophobic space formed by amino acid...

Oligomerization of hantaviral nucleocapsid protein: charged residues in the N-terminal coiled-coil domain contribute to intermolecular interactions.

The nucleocapsid (N) protein of hantaviruses (family Bunyaviridae) is the most abundant component of the virion; it encapsidates genomic RNA segments and participates in viral genome transcription and replication, as well as in virus assembly. During RNA encapsidation, the N protein forms intermediate trimers and then oligomers via 'head-to-head, tail-to-tail' interactions. In previous work, us...

The coiled-coil domain structure of the Sin Nombre virus nucleocapsid protein.

Hantaviruses can cause hemorrhagic fever with a renal syndrome and hantavirus pulmonary syndrome when transmitted to humans. The nucleocapsid protein of hantaviruses encapsidates viral genomic RNA and associates with transcription and replication complexes. Both the amino and carboxy termini of the nucleocapsid protein had been predicted to form trimers prior to the formation of the ribonucleop...
