The host perinuclear region is the host cytoplasmic region just around the host nucleus. Note: This location is defined for viral proteins that appear in the perinuclear region of infected host cells
[Isoform Replicase polyprotein 1ab]: Multifunctional protein involved in the transcription and replication of viral RNAs. Contains the proteinases responsible for the cleavages of the polyprotein. {Curator Inference}. [Non-structural protein 2]: May play a role in the modulation of host cell survival signaling pathway by interacting with host PHB and PHB2 (By similarity). Indeed, these two proteins play a role in maintaining the functional integrity of the mitochondria and protecting cells from various stresses (By similarity). {By
SimilarityUniProtKB:P0C6X7}. [Papain-like protease]: Responsible for the cleavages located at the N-terminus of the replicase polyprotein (By similarity). In addition, PL-PRO possesses a deubiquitinating/deISGylating activity and processes both 'Lys-48'- and 'Lys-63'-linked polyubiquitin chains from cellular substrates (PubMed:25609249). {By
SimilarityUniProtKB:P0C6X7, Experimental EvidencePubMed:25609249}. [Non-structural protein 4]: Plays a role in host membrane rearrangement that leads to creation of cytoplasmic double-membrane vesicles (DMV) necessary for viral replication (By similarity). Alone is able to induce paired membranes (By similarity). Coexpression of nsp3 and nsp4 does not result in the formation of DMVs (By similarity). {By
SimilarityUniProtKB:P0C6Y3}. [3C-like proteinase]: Responsible for the majority of cleavages as it cleaves the C-terminus of replicase polyprotein at 11 sites. Recognizes substrates containing the core sequence [ILMVF]-Q-|- [SGACN]. Inhibited by the substrate-analog Cbz-Val-Asn-Ser-Thr-Leu-Gln- CMK. {ECO:0000255|PROSITE-ProRule:PRU00772}. [Non-structural protein 7]: Forms a hexadecamer with nsp8 (8 subunits of each) that may participate in viral replication by acting as a primase. Alternatively, may synthesize substantially longer products than oligonucleotide primers. {By
SimilarityUniProtKB:P0C6X7}. [Non-structural protein 8]: Forms a hexadecamer with nsp7 (8 subunits of each) that may participate in viral replication by acting as a primase. Alternatively, may synthesize substantially longer products than oligonucleotide primers. {By
SimilarityUniProtKB:P0C6X7}. [Non-structural protein 9]: Plays an essential role in viral replication by forming a homodimer that binds single-stranded RNA. {By
SimilarityUniProtKB:P0C6Y3}. [Non-structural protein 10]: Plays a pivotal role in viral transcription by stimulating both nsp14 3'-5' exoribonuclease and nsp16 2'-O-methyltransferase activities (By similarity). Therefore plays an essential role in viral mRNAs cap methylation (By similarity). {By
SimilarityUniProtKB:P0C6X7}. [RNA-directed RNA polymerase]: Responsible for replication and transcription of the viral RNA genome. {By
SimilarityUniProtKB:P0C6X7}. [Helicase]: Multi-functional protein with a zinc-binding domain in N-terminus displaying RNA and DNA duplex-unwinding activities with 5' to 3' polarity. Activity of helicase is dependent on magnesium. {By
SimilarityUniProtKB:P0C6X7}. [Proofreading exoribonuclease]: Enzyme possessing two different activities: an exoribonuclease activity acting on both ssRNA and dsRNA in a 3' to 5' direction and a N7-guanine methyltransferase activity (By similarity). Acts as a proofreading exoribonuclease for RNA replication, thereby lowering The sensitivity of the virus to RNA mutagens (By similarity). {By
SimilarityUniProtKB:P0C6X7}. [Uridylate-specific endoribonuclease]: Plays a role in viral transcription/replication and prevents the simultaneous activation of host cell dsRNA sensors, such as MDA5/IFIH1, OAS, and PKR (By similarity). Acts by degrading the 5'-polyuridines generated during replication of the poly(A) region of viral genomic and subgenomic RNAs (By similarity). Catalyzes a two-step reaction in which a 2'3'-cyclic phosphate (2'3'-cP) is first generated by 2'-O transesterification, which is then hydrolyzed to a 3'-phosphate (3'-P) (By similarity). If not degraded, poly(U) RNA would hybridize with poly(A) RNA tails and activate host dsRNA sensors (By similarity). {By
SimilarityUniProtKB:P0C6X7}. [2'-O-methyl transferase]: Methyltransferase that mediates mRNA cap 2'-O-ribose methylation to the 5'-cap structure of viral mRNAs. N7-methyl guanosine cap is a prerequisite for binding of nsp16. Therefore plays an essential role in viral mRNAs cap methylation which is essential to evade immune system. {By
