http://purl.uniprot.org/citations/11264369http://www.w3.org/2000/01/rdf-schema#comment"An open reading frame (ORF) overlapping the amino-terminal portion of the Sendai virus (SeV) P ORF in the +1 frame produces a nested set of carboxy-coterminal proteins, C', C, Y1, and Y2, which are referred to collectively as the C proteins. The C proteins are extremely versatile triple-role players; they counteract the antiviral action of interferons (IFNs), inhibit viral RNA synthesis, and are involved in virus assembly. In this study, we established HeLa cell lines stably expressing the C, Y1, and Y2 proteins individually and examined the capacities of these cells to circumvent the antiviral action of alpha/beta IFN (IFN-alpha/beta) and IFN-gamma and to inhibit viral transcription. The assay protocols included monitoring of IFN-alpha/beta-mediated signaling by interferon-stimulated response element-driven reporter gene expression and of the antiviral state induced by IFN-alpha/beta and IFN-gamma and measurement of reporter gene expression from an SeV minigenome, as well as quantification of SeV primary transcripts. When necessary, the activities measured were carefully normalized to the expression levels of the respective C proteins in cells. The data obtained clearly indicate that the smallest protein, Y2, was as active as the C and Y1 proteins in both counteracting the antiviral action of IFNs and inhibiting viral transcription. The data further show that intracellular transexpression of either C, Y1, or Y2 rendered HeLa cells moderately or only poorly permissive for not only wild-type SeV but also 4C(-) SeV, which expressed none of the four C proteins. On the basis of these findings, the roles of SeV C proteins in the natural life cycle are discussed."xsd:string
