| Background: |
AMP-activated protein kinase (AMPK) is highly conserved from yeast to plants and animals and plays a key role in the regulation of energy homeostasis. AMPK is a heterotrimeric complex composed of a catalytic subunit and regulatory and subunits, each of which is encoded by two or three distinct genes (1, 2; 1, 2; 1, 2, 3). |
