Function
[PASK_HUMAN] Serine/threonine-protein kinase involved in energy homeostasis and protein translation. Phosphorylates EEF1A1, GYS1, PDX1 and RPS6. Probably plays a role under changing environmental conditions (oxygen, glucose, nutrition), rather than under standard conditions. Acts as a sensor involved in energy homeostasis: regulates glycogen synthase synthesis by mediating phosphorylation of GYS1, leading to GYS1 inactivation. May be involved in glucose-stimulated insulin production in pancreas and regulation of glucagon secretion by glucose in alpha cells; however such data require additional evidences. May play a role in regulation of protein translation by phosphorylating EEF1A1, leading to increase translation efficiency. May also participate to respiratory regulation.[1] [2] [3] [4] [5] [6]

Publication Abstract from PubMed
PAS domains are sensory modules in signal-transducing proteins that control responses to various environmental stimuli. To examine how those domains can regulate a eukaryotic kinase, we have studied the structure and binding interactions of the N-terminal PAS domain of human PAS kinase using solution NMR methods. While this domain adopts a characteristic PAS fold, two regions are unusually flexible in solution. One of these serves as a portal that allows small organic compounds to enter into the core of the domain, while the other binds and inhibits the kinase domain within the same protein. Structural and functional analyses of point mutants demonstrate that the compound and ligand binding regions are linked, suggesting that the PAS domain serves as a ligand-regulated switch for this eukaryotic signaling system.
