Expression of different subunits of AMPK in human organs. AMPK is widely but distinctly distributed in different tissues and organs. The brain mainly contains the α1, α2, β1, γ1, and γ2 subunits. The heart and liver mainly contain the α1, α2, γ1, and γ2 subunits. The lung and kidney mainly contain the α1, γ1, and γ2 subunits. The skeletal muscle mainly contains the α2, β2, γ1, γ2, and γ3 subunits.
