ATP site-targeting, highly potent and selective phosphatidylinositol 4-kinase type IIIα (PI4KA, PI4KIIIα) inhibitor.
GSK-A1 is an ATP site-targeting, highly potent and selective type III phosphatidylinositol 4-kinase PI4KA (PI4KIIIα) inhibitor (pIC50 = 8.5-9.8) that selectively downregulates cellular PtdIns(4)P, but not PtdIns(4,5)P2, level (HEK293 IC50 = 3 nM, complete depletion of HEK293 & COS-7 plasma membrane PtdIns(4)P by 100 nM post 10 min treatment) with much reduced potency toward PI4KB (pIC50 = 7.2-7.7), PI3KA/B/D/G (pIC50 = 7.3/7/7.1/7.8) or PI4K/2A/2B (pIC50 <5). GSK-A1 is a useful tool for probing PI4KA-dependent cellular processes and viral replication (typical culture treatment conc. range: 10-100 nM).

Encephalomyocarditis virus (EMCV), like hepatitis C virus (HCV), requires phosphatidylinositol 4-kinase IIIα (PI4KA) for genome replication. Here, we demonstrate that tyrphostin AG1478, a known epidermal growth factor receptor (EGFR) inhibitor, also inhibits PI4KA activity, both in vitro and in cells.
Phospholipase C (PLC) enzymes hydrolyze the plasma membrane (PM) lipid phosphatidylinositol 4,5-bisphosphate (PI4,5P2) to generate the second messengers inositol trisphosphate (IP3) and diacylglycerol (DAG) in response to receptor activation in almost all mammalian cells. We previously found that stimulation of

The lipid phosphatidylinositol 4-phosphate (PI4P) plays a master regulatory role at Golgi membranes, orchestrating membrane budding, non-vesicular lipid transport and membrane organization. It follows that harmonious Golgi function requires strictly maintained PI4P homeostasis. One of the most abundant PI4P effector
Positive-strand RNA [(+)RNA] viruses are true masters of reprogramming host lipid trafficking and synthesis to support virus genome replication. Via their membrane-associated 3A protein, picornaviruses of the genus Enterovirus (e.g., poliovirus, coxsackievirus, and rhinovirus) subvert Golgi complex-localized phosphatidylinositol 4-kinase IIIβ
Active membrane remodeling during myelination relies on phospholipid synthesis and membrane polarization, both of which are known to depend on inositol phospholipids. Here, we show that sciatic nerves of mice lacking phosphatidylinositol 4-kinase alpha (PI4KA) in Schwann cells (SCs) show
