'''Phosphatidylinositol 4-kinase''' (PI4K) modulates inter-organelle lipid tarfficking. phosphoinositide signalling and intracellular vescicle trafficking. The catalytic domain of PI4K is required for the synthesis of phosphatidylinositol 4-phosphate<ref>PMID:23608234</ref>. The mammalian PI4K are classified into 2 types - II and III - based on their molecular mass and modulation by detergent and adenosine.<br />
