UniProtKB accession:  A7M6E7

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Inhibitor of viral RNA replication which confers resistance to some tobamoviruses including tomato mosaic virus (ToMV) (e.g. isolate L), tobacco mosaic virus (TMV), tobacco mild green mosaic virus (TMGMV) and pepper mild mottle virus (PMMoV), but not to resistance-breaking isolates of ToMV (e.g. LT1, SL-1 and ToMV1-2) and tomato brown rugose fruit virus (ToBRFV) (PubMed:17699618, PubMed:3686829, PubMed:17238011, PubMed:19423673, PubMed:23415925, PubMed:29582165, PubMed:28107419). Prevents tobamoviruses RNA replication by affecting the association of tobamoviruses replication proteins (large and small subunits) with host membrane-associated proteins (e.g. TOM1, TOM2A and ARL8), thus inhibiting the replication complex formation on the membranes and avoiding viral negative-strand RNA synthesis (PubMed:17699618, PubMed:19423673, PubMed:23658455, PubMed:23415925). Inhibits triphosphatase activity of ToMV replication proteins (PubMed:25092327).
