RESUMO

A previously unrecognized gene (SH) has been identified on the virion RNA of the paramyxovirus simian virus 5 between the genes for the fusion protein and the hemagglutinin-neuraminidase. An SH mRNA of 292 nucleotides (plus polyadenylate residues), transcribed from the SH gene, has been identified. The SH mRNA contains a single open reading frame which encodes a polypeptide of 44 amino acids with a molecular weight of 5,012. The SH polypeptide is predicted to contain an extensive hydrophobic region. This protein has been identified in simian virus 5-infected cells, and it has been shown to be encoded by the SH mRNA by in vitro translation of size-fractionated mRNAs, hybrid-arrest translation, and hybrid-selection translation.
