The phosphatidylinositol 4-kinases (PI4Ks) synthesize phosphatidylinositol 4-phosphate (PI4P), a key member of the phosphoinositide family. PI4P defines the membranes of Golgi and trans-Golgi network (TGN) and regulates trafficking to and from the Golgi. In mammals there are four different PI4K enzymes, two type II enzymes (PI4KIIα and PI4KIIβ) and two type III enzymes (PI4KIIIα and PI4KIIIβ). PI4KIIIβ plays key roles in mediating lipid transport, cytokinesis, maintaining lysosomal identity, and in tandem with Rab GTPases plays key roles in regulating membrane trafficking. PI4KIIIβ is critical for mediating viral replication of a number of RNA viruses through the generation of PI4P enriched viral replication platforms. Small molecule inhibitors of PI4KIIIβ are potent anti-viral agents. Development of PI4KIIIβ as an effective drug target for anti-viral therapeutics requires the generation of highly potent and specific inhibitors.
