Hantavirus Nucleocapsid Protein Oligomerization

Hantavirus nucleocapsid protein oligomerization.

Hantaviruses are enveloped, negative-strand RNA viruses which can be lethal to humans, causing either a hemorrhagic fever with renal syndrome or a hantaviral pulmonary syndrome. The viral genomes consist of three RNA segments: the L segment encodes the viral polymerase, the M segment encodes the viral surface glycoproteins G1 and G2, and the S segment encodes the nucleocapsid (N) protein. The N...

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

Interaction between molecules of hantavirus nucleocapsid protein.

Intermolecular interactions of Tula hantavirus N (nucleocapsid) protein were detected in the yeast two-hybrid system, prompting further attempts to study this phenomenon. Using chemical cross-linking and immunoblotting it was shown that the N protein from purified virus and from infected cell lysates as well as recombinant protein produced in a baculovirus expression system are capable of formi...
