In this study, we investigated the genomic characteristics of a NeV strain from yaks that has a novel RdRp genotype. The complete genome of this strain (YAK/NRG-A9/19/CH) is 7454 nt in length and shares 68.3%-79.7% nt sequence identity with those of other NeVs. The RNA-dependent RNA polymerase (RdRp) gene of this strain shares 66.5%-78.5% nt sequence identity (74.0%-89.3% aa sequence identity) with the eight available complete NeV RdRp sequences, and a phylogenetic analysis based on these sequences showed that the new strain formed an independent branch, indicating that the RdRp of strain YAK/NRG-A9/19/CH may represent a novel RdRp genotype of NeV. These results contribute to a further understanding of the molecular characteristics and genetic evolution of NeVs.Complement component 1 Q subcomponent-binding protein (C1QBP) has been shown to interact with the porcine circovirus type 2 (PCV2) Cap protein. Here, using yeast two-hybrid (Y2H) and co-immunoprecipitation assays, as well as laser confocal microscopy, the interaction between C1QBP and Cap was confirmed. Furthermore, overexpression of C1QBP in cells altered the intracellular location of Cap, which was observed using confocal microscopy and verified by detection of Cap in nuclear protein extracts in a Western blot assay. By inhibiting nuclear transport of Cap, overexpression of C1QBP downregulated PCV2 proliferation in PK-15 cells, as determined by quantitative polymerase chain reaction (qPCR). As C1QBP plays a similar role in a fusion of green fluorescent protein (GFP) with the Cap nuclear localisation signal (NLS) sequence, (CapNLS-GFP), we propose that the target site for C1QBP in Cap is possibly located in the NLS region. Considering all the results together, this study demonstrated that C1QBP interacts with the Cap NLS region, resulting in changes in
