Polyprotein processing
WebIn the programmed oocytes, there is correct viral translation, polyprotein processing and assembly of capsid proteins leading to the production of infectious TMEV. The vast majority of de novo synthesised virions were found in the medium in which the programmed oocytes were incubated and not in the oocytes. WebYF17D is an ssRNA flavivirus that is translated as a full-length polyprotein, several domains of which pass into the lumen of the endoplasmic reticulum (ER). The processing and presentation machinery for MHC class I-restricted CTL responses favor cytoplasmic peptides that are transported into the ER by the transp...

WebSep 25, 2012 · Abstract. Alphaviruses, a group of positive-sense RNA viruses, are globally distributed arboviruses capable of causing rash, arthritis, encephalitis, and death in humans. The viral replication machinery consists of four nonstructural proteins (nsP1–4) produced as a single polyprotein. Processing of the polyprotein occurs in a highly regulated ... WebAug 16, 2024 · To maximize a limited genetic capacity, viruses encode polyproteins that can be subsequently separated into individual components by viral proteases. While classically viewed as a means of economy, recent findings have indicated that polyprotein processing can spatially and temporally coordinate the distinct phases of the viral life cycle.
WebLike many RNA viruses, hepatitis C virus (HCV) hijacks cellular ribosomes and forces them to make a long viral polyprotein, which must then be clipped into functional pieces by a viral protease (for other examples, see HIV protease and coronavirus proteases).Since these proteases have a central function in the viral life cycle, they are effective targets for … WebJan 5, 2004 · Polyprotein processing is a major strategy used by many viruses to generate many functional protein products from a single open reading frame (Wellink and van …
