Bioinformatics Analysis Identifies a Small ORF in the Genome of Fish Nidoviruses of Genus Oncotshavirus Predicted to Encode a Novel Integral Protein

Genome sequence analysis of Atlantic salmon bafinivirus (ASBV) revealed a small open reading frame (ORF) predicted to encode a Type I membrane protein with an N-terminal cleaved signal sequence (110 aa), likely an envelope (E) protein. Bioinformatic analyses showed that the predicted protein is stri...

Description
Summary:Genome sequence analysis of Atlantic salmon bafinivirus (ASBV) revealed a small open reading frame (ORF) predicted to encode a Type I membrane protein with an N-terminal cleaved signal sequence (110 aa), likely an envelope (E) protein. Bioinformatic analyses showed that the predicted protein is strikingly similar to the coronavirus E protein in structure. This is the first report to identify a putative E protein ORF in the genome of members of the Oncotshavirus genus (subfamily Piscavirinae, family Tobaniviridae, order Nidovirales) and, if expressed would be the third family (after Coronaviridae and Arteriviridae) within the order to have the E protein as a major structural protein.
