dc.description.abstract | Singapore grouper iridovirus (SGIV) is an enveloped virus causing heavy economic losses to marine fish culture. The envelope fractions of SGIV were separated from the purified virions by Triton X-100 treatment, and subjected to 1-DE-MALDI-TOF/TOF-MS/MS and LC-MALDI-TOF/TOF-MS/MS analysis. A total of 19 virus-encoded envelope proteins were identified in this study and 73.7% (13/17) of them were predicted to be membrane proteins. Three viral envelope proteins were uniquely identified by 1-DE-MALDI, whereas another ten proteins were identified only by LC-MALDI, with six proteins identified by both workflows. VP088 was chosen as a representative of proteomic identification and characterized further. VP088 was predicted to be a viral transmembrane envelope protein which contains two RGD (Arg-Gly-Asp) motifs, three transmembrane domains, and five N-glycosylation sites. VP088 gene transcript was first detected at 12h p.i. and reached the peak at 48h p.i. Combined with the drug inhibition assay, VP088 gene was identified as a late (L) gene. Recombinant VP088 (rVP088) was expressed in Escherichia coli, and the specific antiserum against rVP088 was raised. VP088 was proved to be a viral envelope protein by Western blot and immunoelectron microscopy (IEM). Furthermore, rVP088 can bind to a 94kDa host cell membrane protein, suggesting that VP088 might function as an attaching protein. Neutralization assay also suggested that VP088 is involved in SGIV infection. This study will lead to a better understanding of molecular mechanisms of the iridoviral pathogenesis and virus-host interactions. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. | |
