Authors: Igor Moshynskyy 1, Sathiyanarayanan Viswanathan, Natalia Vasilenko, Vladislav Lobanov, Martin Petric, Lorne A Babiuk, Alexander N Zakhartchouk Abstract Open reading frame 9b (ORF 9b) encodes a 98 amino acid group-specific protein of severe acute respiratory syndrome (SARS) coronavirus (CoV). It has no homology with known proteins and its function in SARS CoV replication has not been determined. The N-terminal part of […]

RaduAricescu13ReneAssenberg2Robin T.Aplin2Robert J.C.Gilbert13Jonathan M.Grimes123David I.Stuart123 Summary To achieve the greatest output from their limited genomes, viruses frequently make use of alternative open reading frames, in which translation is initiated from a start codon within an existing gene and, being out of frame, gives rise to a distinct protein product. These alternative protein products are, as yet, […]

Protein: ORF9b protein database Gene: 9b Organism Severe acute respiratory syndrome coronavirus (SARS-CoV) Status Reviewed-Annotation score:-Experimental evidence at protein leveli Functioni Plays a role in the inhibition of host innate immune response by targeting the mitochondrial-associated adapter MAVS. Mechanistically, usurps the E3 ligase ITCH to trigger the degradation of MAVS, TRAF3, and TRAF6. In addition, […]

.J Immunol 2014 Sep 15;193(6):3080-9. doi: 10.4049/jimmunol.1303196. Epub 2014 Aug 18. Chong-Shan Shi 1, Hai-Yan Qi 2, Cedric Boularan 1, Ning-Na Huang 1, Mones Abu-Asab 3, James H Shelhamer 2, John H Kehrl 4 Abstract Coronaviruses (CoV) have recently emerged as potentially serious pathogens that can cause significant human morbidity and death. The severe acute respiratory syndrome (SARS)-CoV was identified as the etiologic agent of the 2002-2003 international SARS outbreak. […]
