Virus proteins, sizes and functional activities.
| Protein | size (kDa) | mRNA | Function1 |
|---|---|---|---|
| 1a | 102.7-125.8 | RNA-1 | Mtr, helicase |
| 2a | 89.8-96.7 | RNA-2 | RdRp |
| 3a | 30.5-36.5 | RNA-3 | cell to cell movement |
| CP | 19.8-26.2 | sgRNA-42 | encapsidation, movement |
Functions of 1a and 2a are putative in most cases, by analogy to related viruses
The sgRNA for the CP derived from RNA-3 is encapsidated in all but the genus Oleavirus.
