Polyclonal Rabbit Affinity Purified B
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 1). AMPK is a heterotrimeric complex composed of a catalytic a subunit and regulatory b and g subunits, each of which is encoded by two or three distinct genes a1, 2; b1, 2; g1, 2, 3) (2). The kinase is activated by an elevated AMP/ATP ratio due to cellular and environmental stress, such as heat shock, hypoxia and
ischemia (1). Tumor suppressor LKB1, in association with accessory proteins STRAD and MO25, phosphorylates AMPK at Thr172 at the activation loop, and this phosphorylation is required for AMPK activation (35). AMPKa is also phosphorylated at Thr258 and Ser485 for a1; Ser491 for a2). The upstream kinase and the biological significance of these phosphorylation events
have yet to be elucidated (6). The b1 subunit is posttranslationally modified by myristoylation and multi-site phosphorylation including Ser24/25, Ser96, Ser101, Ser108, and Ser182 (6,7). Phosphorylation at Ser108 of the b1 subunit seems to be required for the activation of
AMPK enzyme, while phosphorylation at Ser24/25 and Ser182 affects AMPK localization (7). Several mutations in AMPKg subunits have been identified, most of which are located in the putative AMP/ATP binding sites (CBS or Bateman domains). Mutations at these sites lead to
reduction of AMPK activity and cause glycogen accumulation in heart or skeletal muscle (1,2). Accumulating evidence indicates that AMPK not only regulates the metabolism of fatty acids and glycogen, but also modulates protein synthesis and cell growth through EF2 and TSC2/mTOR pathways, as well as blood flow via eNOS/nNOS (1).
