Structural highlights
Function
[WAC_BPT4] Chaperone responsible for attachment of long tail fibers to virus particle. Forms the fibrous structure on the neck of the virion called whiskers. During phage assembly, 6 fibritin molecules attach to each virion neck through their N-terminal domains, to form a collar with six fibers ('whiskers').

Publication Abstract from PubMed
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 ribonucleoprotein. Crystal structures of amino-terminal fragments of the nucleocapsid protein showed the formation of intramolecular antiparallel coiled coils, but not intermolecular trimers. Thus, the amino-terminal part of the nucleocapsid protein is probably insufficient to initiate the trimerization of the full-length molecule.
