RN [1] RP NUCLEOTIDE SEQUENCE [GENOMIC RNA]. RC STRAIN=V; RX PubMed=1895056; RA Bernal J.J., Moriones E., Garcia-Arenal F.; RT "Evolutionary relationships in the cucumoviruses: nucleotide sequence RT of tomato aspermy virus RNA 1."; RL J. Gen. Virol. 72:2191-2195(1991). CC -!- FUNCTION: Involved in the virus replication. Contains a helicase CC domain and a methyltransferase domain. The methyltransferase CC domain is probably involved in viral RNA capping. Involved in the CC formation of ER membrane spherular invaginations in which RNA CC replication complexes form (By similarity). {ECO:0000250}. CC -!- SUBUNIT: Interacts with RNA-directed RNA polymerase 2a. CC {ECO:0000250}. CC -!- SUBCELLULAR LOCATION: Host endoplasmic reticulum membrane CC {ECO:0000250}; Peripheral membrane protein {ECO:0000250}. CC -!- SIMILARITY: Belongs to the bromoviridae replication protein 1a CC family. {ECO:0000305}. CC -!- SIMILARITY: Contains 1 (+)RNA virus helicase ATP-binding domain. CC {ECO:0000305}. CC -!- SIMILARITY: Contains 1 (+)RNA virus helicase C-terminal domain. CC {ECO:0000305}.
