title: Nucleotide sequence of human rotavirus genome segment 10, an RNA encoding a glycosylated virus protein.
abstract: The complete nucleotide sequence of human rotavirus (Wa strain) genome segment 10 was determined by using a cloned DNA copy. The sequence data indicated that segment 10 is A + T rich (65%) and consists of 750 base pairs. The positive strand of segment 10 contains a single open reading frame that extends 175 codons from the first AUG triplet (residues 42 through 44). The amino acid sequence of the segment 10 product was deduced from the nucleotide sequence. There are two distinct glycosylation sites at the N-terminal hydrophobic region, consistent with previous findings that this protein exists in a glycosylated form. The apparent molecular weight (20,000) of the unglycosylated, precursor polypeptide is in good agreement with the one calculated from the predicted amino acid sequence. Structural analysis of the positive strand (mRNA from segment 10) showed that it could form, like mRNA from segment 11, a stable panhandle structure involving the 5' and 3'-terminal regions. The nucleotide sequence of segment 10 from simian rotavirus, recently determined by Both et al. (J. Virol. 48:335-339, 1983) was found to be highly homologous to, and to share several important features with, segment 10 of human rotavirus.
