Understanding how hepatitis C virus builds its unctuous home

Brett D Lindenbach. Cell Host Microbe. .

Abstract

Hepatitis C virus genome replication occurs in endoplasmic reticulum-derived membrane compartments, but it is unknown how these structures arise. In this issue of Cell Host & Microbe, Reiss and colleagues (2011) show that the virus recruits a specific lipid kinase to replication sites, stimulates its kinase activity, and alters the phospholipid profile of replication compartments.

Figure 1. PI4KIIIα Is Needed for HCV Replication Complex Assembly
(A and B) HCV RNA replication is thought to take place within invaginations of an ER-derived membrane. The viral NS3-4A, NS4B, NS5A, and NS5B proteins are all essential for this process (A). NS5A binds and activates PI4KIII, leading to the local production of PI4P (B). One possibility is that PI4P then recruits viral or cellular factors that are essential for forming the replication compartment.
