Gene Ontology Information

Protein Name	Pik1p
Description	Phosphatidylinositol 4-kinase; catalyzes the first step in the biosynthesis of phosphatidylinositol-4,5-biphosphate; may control cytokinesis through the actin cytoskeleton; required for autophagosome formation during autophagy and for lipophagy in both stationary phase cells and during nitrogen starvation; may control nonselective autophagy and mitophagy through trafficking of Atg9p; localizes to the nucleus and to the trans-Golgi network
GO Terms: Biological Process	level 6: phosphatidylinositol-mediated signaling level 6: microlipophagy level 6: phosphorylation level 8: phosphatidylinositol phosphate biosynthetic process level 8: positive regulation of autophagosome assembly
GO Terms: Molecular Function	level 3: transferase activity level 4: nucleotide binding level 5: kinase activity level 5: phosphotransferase activity, alcohol group as acceptor level 6: ATP binding level 6: phosphatidylinositol kinase activity level 7: 1-phosphatidylinositol 4-kinase activity
GO Terms: Cellular Component	level 3: cytoplasm level 3: membrane level 5: nucleus level 5: trans-Golgi network
