Hepatitis B virus (HBV) infection leads tdevelopment of fatal liver complications. Due to a lack of effective measure to cure HBV infection, complete eradication of HBV is difficult. Thus, novel HBV therapeutic strategies are needed. Host proteins involved in the HBV infection processes are known to be regulated through phosphorylation. System level changes in phospho-signaling pathway in host during infection remains unclear. To this end, phosphoproteome profiling on HBV infected HepG2-NTCP cells was performed.
