Chutes and Ladders: the search for protein kinases that act on AMPK.

Published

Journal Article (Review)

AMP-activated protein kinase (AMPK), a key regulator of energy homeostasis in mammalian cells, is, in turn, regulated by long-sought upstream protein kinases (AMPKKs). Following the recent identification of the tumor-suppressor kinase LKB1 as an AMPKK, a broader role for AMPK in metabolic economy has been unveiled by a new body of work from three groups that implicates the Ca(2+)/calmodulin-dependent protein kinase kinases as AMPKKs. We suggest that PKE (protein kinase "energy" or "economy") is now an apt name for this kinase, which regulates both cellular and whole-organism energy homeostasis.
