Abstract

Per-Arnt-Sim (PAS) kinase (PASK, PASKIN, and PSK) is a member of the group of nutrient sensing protein kinases. These protein kinases sense the energy or nutrient status of the cell and regulate cellular metabolism appropriately. PAS kinase responds to glucose availability and regulates glucose homeostasis in yeast, mice, and man. Despite this pivotal role, the molecular mechanisms of PAS kinase regulation and function are largely unknown. This review focuses on what is known about PAS kinase, including its conservation from yeast to man, identified substrates, associated phenotypes and role in metabolic disease. © 2013 IUBMB Life, 65(11):921–929, 2013
