The 5-AMP-activated protein kinase (AMPK) is a key sensor of intracellular
energy balance. AMPK is activated in response to an increase in the
AMP/ATP ratio which can be caused by a number of factors such as
muscle contraction, starvation, or hypoxia. AMPK is a heterotrimeric protein
complex comprising of α- (63 kDa), β- (38 kDa) and γ- (38 kDa) subunits.
For each subunit, isoforms have been identified (α1, α2, β1, β2, γ1, γ2, γ3)
which theoretically allow the formation of 12 different proteins. The α-
subunit contains a serine/threonine kinase domain and the regulatory
subunits contain binding sites for AMP and ATP (γ-subunit) and for
glycogen (β-subunit).
AMPK is activated by phosphorylation on Thr-172 within the catalytic
domain. AMP binding results in a 2 to 5-fold increase in AMPK activity
compared to the basal level. Binding of AMP to the γ-subunit causes
allosteric activation of the kinase and induces a conformational change in
the kinase domain that protects AMPK from dephosphorylation of Thr-172.
BioAssay Systems' cell-based ELISA measures phosphorylated AMPK in
whole cells and normalizes the signal to the total protein content. The
antibody recognizes both α-subunits and thus can be used for cells from all
tissues (human, mouse, rat). This simple and efficient assay eliminates the
need for cell lysate preparation and can be used to study AMPK regulation
in short-term and long-term assays. In this assay, cells grown in 96-well
plates are fixed and permeabilized in the wells. AMPK phosphorylation
(pAMPK) is measured using a fluorescent ELISA followed by total protein
measurement in each well.
