WebFeb 20, 2024 · IRESs are frequently identified in cellular mRNAs of genes involved in stress responses and are subdivided into two types: Type I cellular IRESs harbor cis-regulatory elements that interact with... WebThe phenomenon of internal initiation of translation was discovered in 1988 on poliovirus mRNA. The prototypic cis-acting element in the 5′ untranslated region (5′UTR) of poliovirus mRNA, which is able to direct initiation at an internal start codon without the involvement of a cap structure, has been called an IRES (Internal Ribosome Entry Site or …
Web2 of 22 46 the first IRES mediated by the 5’ leader of a cellular mRNA was described in 1991 [11]. Interestingly 47 this messenger codes for the immunoglobulin heavy-chain binding protein (BiP), a chaperone 48 involved in the unfolded protein response occurring during endoplasmic reticulum (ER) stress. 49 Although this first cellular mRNA IRES was … WebThe phenomenon of internal initiation of translation was discovered in 1988 on poliovirus mRNA.

WebIn this study, we now evaluate the role of Staufen1 as an HIV-1 IRES-transacting factor (ITAF). We first confirm that Staufen1 associates with both the HIV-1 vRNA and the Gag protein during HIV-1 replication. We found that in HIV-1-expressing cells, siRNA-mediated depletion of Staufen1 reduces HIV-1 vRNA translation. WebNov 28, 2016 · IRES trans-acting factors (ITAFs) are known to participate in such cap-independent translation, but there are gaps in the understanding as to how ITAFs, particularly negative ITAFs, regulate IRES-driven translation. This study found that Lys109, Lys121 and Lys122 represent critical ubiquitination sites for far upstream element-binding …
WebJan 17, 2024 · Notwithstanding, we noticed that the IRES element not only recruited translation factors and IRES-transacting factors but also proteins involved in ER-Golgi transport, as exemplified in Table 1. Following uncoating, the first intracellular step of picornavirus life cycle requires translation of the viral genome, which is governed by the …
