Abstract

Abstract We present the sequence of an open reading frame (ORF) at the 3′ end of human astrovirus serotype 1. Primer extension experiments showed that the RNA expressing this gene is shorter than the complete ORF, and could form a protein of M r 85 540. The protein was expressed by recombinant baculovirus and was recognized by anti‐virion serum, indicating a structural role. Sequence comparison indicates that astrovirus serotypes 1 and 2 differ markedly in the C‐terminal half of the protein but are well conserved towards the N‐terminus.
