Insights into the mechanism of SARS-CoV-2 main protease autocatalytic maturation from model precursors

open access: yesCommunications Biology, 2023
A critical step for SARS-CoV-2 assembly and maturation involves the autoactivation of the main protease (MProWT) from precursor polyproteins. Upon expression, a model precursor of MProWT mediates its own release at its termini rapidly to yield a mature ...

Signaling Pathway Reporter Screen with SARS-CoV-2 Proteins Identifies nsp5 as a Repressor of p53 Activity

open access: yesViruses, 2022
The dysregulation of host signaling pathways plays a critical role in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and viral pathogenesis. While a number of viral proteins that can block type I IFN signaling have been identified,

Phosphorylation Generates Different Forms of Rotavirus NSP5

open access: yesJournal of General Virology, 1996
NSP5 (non-structural protein 5) is one of two proteins encoded by genome segment 11 of group A rotaviruses. In virus-infected cells NSP5 accumulates in the virosomes and is found as two polypeptides with molecular masses of 26 and 28 kDa (26K and 28K proteins).

Influence of nut shell powder content on the tribological properties of recycled polyolefin composites [PDF]

open access: yes, 2016
The purpose of this study is to investigate the influence of nut shell powder (NSP) content on the tribological properties of recycled polyolefin (R-PO) composites. NSP was previously grinded the dried nut shell by crusher machine cryogenically in liquid

Rotavirus NSP5 orchestrates recruitment of viroplasmic proteins

open access: yesJournal of General Virology, 2010
Rotavirus genome replication and the first steps of virus morphogenesis take place in cytoplasmic viral factories, called viroplasms, containing four structural (VP1, VP2, VP3 and VP6) and two non-structural (NSP2 and NSP5) proteins. NSP2 and NSP5 have been shown to be essential for viroplasm formation and, when co-expressed in uninfected cells, to ...

Novel G9 rotavirus strains co-circulate in children and pigs, Taiwan [PDF]

open access: yes, 2017
Molecular epidemiologic studies collecting information of the spatiotemporal distribution of rotavirus VP7 (G) and VP4 (P) genotypes have shown evidence for the increasing global importance of genotype G9 rotaviruses in humans and pigs.
