pubmed:abstractText |
Black Creek Canal virus (BCCV) is a New World hantavirus which is associated with hantavirus pulmonary syndrome. We have examined the site of expression of the BCCV nucleocapsid protein (NBCCV) in the absence of BCCV glycoproteins and found that the majority of the protein is localized to the Golgi region. Immunofluorescence analysis of BHK21 cells expressing the NBCCV and La Crosse virus nucleocapsid protein (NLACV) showed different intracellular localization patterns of these proteins within the same cell: NLACV is cytoplasmic, whereas NBCCV is perinuclear. NBCCV was found to be colocalized with alpha-mannosidase II, a marker for the Golgi complex. Also, NBCCV was found to be associated with microsomal membranes following cell fractionation. Sedimentation analysis in density gradients revealed that the membrane association of NBCCV is sensitive to treatments with high-salt and high-pH solutions, which indicates that NBCCV is a peripheral membrane protein. Analysis of NBCCV truncation mutants revealed that the 141-amino-acid C-terminal portion of this protein was capable of targeting green fluorescent protein to the perinuclear region. The difference in the intracellular localization between the NBCCV and NLACV proteins suggests that the mechanisms involved in the morphogenesis of New World hantaviruses are distinct from that documented for other members of the Bunyaviridae family.
