How do ddhctp inhibit viral translation
WebDec 9, 2024 · While the OAS/RNase L pathway globally degrades RNA and arrests translation, ISG20 and ZAP employ targeted RNA degradation and translation inhibition to block viral replication. Meanwhile, SHFL targets translation by inhibiting -1 ribosomal frameshifting, which is required by many RNA viruses.

WebddhCTP has been shown to act as a chain terminator for viral RNA-dependent RNA polymerases (RdRp) from multiple Flavivirus members19, and this offers an explanation for viperin’s ability to broadly limit this viral genus (reviewed by Helbig & Beard 6). However, ddhCTP is unable to inhibit WebA defining attribute of virus infection biology is its absolute reliance on the host translation machinery to produce the polypeptides needed for virus reproduction. This feature cannot be overstated, as virus replication and spread depend on conscripting host ribosomes to translate viral messenger RNAs (mRNAs).
