The location and function of individual proteins may be drawn from similarities other fijivirus proteins or other members of the family Reoviridae

': Protein structure/function: RNA polymerase = (Pol); viral inclusion body or viroplasm matrix protein = (ViP).

* Other isolates and species within the genus may have proteins with significant differences in sizes.

Segments numbered based on migration of genome segments in SDS-PAGE gel. Migration order differs among other members of the genus. Updated August 2003
