Protein

Genome polyprotein

Gene

ORF1

Organism
San Miguel sea lion virus serotype 1 (SMSV-1) (SMSV serotype 1)
Status
Reviewed - Annotation score: 4 out of 5- Protein inferred from homologyi

Functioni

NTPase presumably plays a role in replication. Despite having similarities with helicases, does not seem to display any helicase activity (By similarity).By similarity
Viral genome-linked protein is covalently linked to the 5'-end of the positive-strand, negative-strand genomic RNAs and subgenomic RNA. Acts as a genome-linked replication primer. May recruit ribosome to viral RNA thereby promoting viral proteins translation (By similarity).By similarity
Protease-polymerase p76 processes the polyprotein: Pro-Pol is first released by autocleavage, then all other proteins are cleaved. Cleaves host translation initiation factor eIF4G1 and eIF4G2 thereby inducing a shutdown of host protein synthesis. This shutdown may not prevent viral mRNA from being translated since viral Vpg replaces the cap. May cleave host polyadenylate-binding protein thereby inhibiting cellular translation. It is also an RNA-directed RNA polymerase which replicates genomic and antigenomic viral RNA by recognizing specific signals. Transcribes also a subgenomic mRNA by initiating RNA synthesis internally on antigenomic RNA. This sgRNA codes for structural proteins. Catalyzes the covalent attachment VPg with viral RNAs (By similarity).By similarity

Catalytic activityi

NTP + H2O = NDP + phosphate.
Endopeptidase with a preference for cleavage when the P1 position is occupied by Glu-|-Xaa and the P1' position is occupied by Gly-|-Yaa.
Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1).PROSITE-ProRule annotation
