SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm,organelle,mitochondria,interspace
	intracellular,cytoplasm,cytosolic
text	PANK2 short GFP in the cytoplasm only
	PANK2 long GFP in the mitochondria and nucleus

basic FUNCTION	a mitochondrial enzyme that catalyses the first regulatory step of Coenzyme A synthesis
	catalyzing the cytosolic phosphorylation of pantothenate (vitamin B5) and derivatives
	essential regulatory enzyme in coenzyme A biosynthesis
	plays a central role in phospholipid synthesis and membranogenesis
	encodes a mitochondrial protein involved in Coenzyme A synthesis
	PANK1 and PANK2 can compensate for each other to supply tissue CoA, but PANK1 is more important to CoA levels in liver whereas PANK2 contributes more to CoA synthesis in the brain
