| Subcellular Location | SUBCELLULAR LOCATION: [Viral genome-linked protein]: Host endoplasmic reticulum lumen {ECO:0000305}.; SUBCELLULAR LOCATION: [Putative ATP-dependent helicase]: Host endoplasmic reticulum membrane; Single-pass membrane protein. Note=The NTB-VPg polyprotein is associated with endoplasmic-derived membranes that are active in viral replication. |
| Modified Residue | |
| Post Translational Modification | PTM: Specific enzymatic cleavages by picornain 3C-like protease in vivo yield mature proteins. Picornain 3C-like protease is autocatalytically processed. NTB exists as NTB-VPg polyprotein as well as NTB mature protein. {ECO:0000269|PubMed:10092022, ECO:0000269|PubMed:11038391}.; PTM: VPg is uridylylated by the polymerase and is covalently linked to the 5'-end of genomic RNA. This uridylylated form acts as a nucleotide-peptide primer for the polymerase (By similarity). {ECO:0000250}. |
