Fig. 2From: The MAPK and AMPK signalings: interplay and implication in targeted cancer therapyAMPK signaling and its downstream effectors. AMPK is activated by liver kinase B1 (LKB1) or calcium/calmodulin-dependent protein kinase kinase 2 (CAMKK2/β) through phosphorylation on Thr172 of α subunit and is inactivated through dephosphorylation of this site by protein phosphatases in response to changes of cellular AMP:ADP:ATP ratio. Downstream effectors activated by AMPK are indicated as arrows, and those inhibited by AMPK are shown as bar-headed linesBack to article page
