Table 1. Paramyxovirus accessory proteins of interest.
Rubulavirus V proteins (underlined) are the primary transcripts, with P/I proteins being produced through mRNA editing. For all other genera, P proteins (underlined) are the primary transcript, with V/W/D proteins produced through mRNA editing.
C proteins are produced from alternate start codons of the P ORF and are translated in a different open reading frame.
SeV and HPIV-1 produce additional alternate start codon proteins in the same reading frame as C, named C', Y1, and Y2. They share the majority of their sequence with C, but with slightly longer (C') or shorter (Y1, Y2) N termini.
