Phosphatidylinositol 4-kinase III beta crystallized with MI103 inhibitor

Structural highlights

4wag is a 1 chain structure with sequence from Human. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Ligands:
Gene:	PI4KB, PIK4CB (HUMAN)
Activity:	1-phosphatidylinositol 4-kinase, with EC number 2.7.1.67
Resources:	FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

[PI4KB_HUMAN] Phosphorylates phosphatidylinositol (PI) in the first committed step in the production of the second messenger inositol-1,4,5,-trisphosphate (PIP). May regulate Golgi disintegration/reorganization during mitosis, possibly via its phosphorylation. Involved in Golgi-to-plasma membrane trafficking (By similarity).^[1] ^[2] ^[3]

Publication Abstract from PubMed

Phosphatidylinositol 4-kinase IIIbeta is a cellular lipid kinase pivotal to pathogenesis of various RNA viruses. These viruses hijack the enzyme in order to modify the structure of intracellular membranes and use them for the construction of functional replication machinery. Selective inhibitors of this enzyme are potential broad-spectrum antiviral agents, as inhibition of this enzyme results in the arrest of replication of PI4K IIIbeta-dependent viruses. Herein, we report a detailed study of novel selective inhibitors of PI4K IIIbeta, which exert antiviral activity against a panel of single-stranded positive-sense RNA viruses. Our crystallographic data show that the inhibitors occupy the binding site for the adenine ring of the ATP molecule and therefore prevent the phosphorylation reaction.
