Dear Editor,

Mammalian cells encode five members of the nucleosome assembly protein 1 (NAP1) family of proteins including nucleosome assembly protein 1-like 1 (NAP1L1), NAP1L2, NAP1L3, NAP1L4 and NAP1L5 (Attia et al. 2011). NAP1L1 is ubiquitously expressed and has been implicated in several processes of transcription and DNA replication, such as the nucleosome assembly, nucleosome sliding, transcriptional activation through chromatin remodeling, and nucleocytoplasmic shuttling of histones (Lee et al. 2017; Moshkin et al. 2009; Zlatanova et al. 2007). Furthermore, NAP1L1 is involved in the life cycle of several DNA viruses (EBV, KSHV and HPV) (Gupta et al. 2016; Rehtanz et al. 2004; Wang and Frappier 2009) and retroviruses (HIV and HTLV) (Sharma and Nyborg 2008; Vardabasso et al. 2008). An interesting but yet unanswered question is whether NAP1L1 is involved in the life cycle of RNA viruses.

Hepatitis C virus (HCV) encoded a 9.6-kb positive-sense RNA genome and is classified as the Hepacivirus...
