CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000305}.
CC   -!- DOMAIN: Late-budding domains (L domains) are short sequence motifs
CC       essential for viral particle budding. They recruit proteins of the host
CC       ESCRT machinery (Endosomal Sorting Complex Required for Transport) or
CC       ESCRT-associated proteins. Gag contains one L domain: a PPXY motif
CC       which potentially interacts with the WW domain 3 of NEDD4 E3 ubiquitin
CC       ligase (Potential). {ECO:0000305}.
CC   -!- MISCELLANEOUS: This protein is a product of the Gag-Ros or p19-Ros
CC       polyprotein.
