PRMT5 restricts hepatitis B virus replication through epigenetic repression of covalently closed circular DNA transcription and interference with pregenomic RNA encapsidation
Wen Zhang, Jieliang Chen, Min Wu, Xiaonan Zhang, Min Zhang, Lei Yue, Yaming Li, Jiangxia Liu, Baocun Li, Fang Shen, Yang Wang, Lu Bai, Ulrike Protzer, Massimo Levrero, Zhenghong Yuan – 25 February 2017 – Chronic hepatitis B virus (HBV) infection remains a major health problem worldwide. The covalently closed circular DNA (cccDNA) minichromosome, which serves as the template for the transcription of viral RNAs, plays a key role in viral persistence.
