WebMay 9, 2024 · The ambisense nature of gene expression in arenaviruses results in both genomes (vRNA) and antigenomes (cRNA) functioning as templates for mRNA synthesis. The two promoters are related in sequence, with only two differences over 19 nt ( Fig. 2 A, CONS and cRNA sequences). WebOct 29, 2015 · Replication of influenza viral genomic RNA (vRNA) is catalyzed by viral RNA-dependent RNA polymerase (vRdRP). Complementary RNA (cRNA) is first copied from vRNA, and progeny vRNAs are then amplified from the cRNA.

WebMar 9, 2024 · The influenza A virus genome consists of eight segments of negative-sense RNA that encode up to 18 proteins. During the process of viral replication, positive-sense (+)RNA (cRNA) or messenger RNA (mRNA) is synthesized. Today, there is only a partial understanding of the function of several secondary structures within vRNA and cRNA … WebJan 16, 2024 · Here, we find that influenza polymerase requires ANP32 proteins to support both steps of genome replication: cRNA and vRNA synthesis. However, avian strains are only restricted in vRNA synthesis in human cells. Therefore, avian influenza polymerase can use human ANP32 orthologues to support cRNA synthesis, without acquiring …
