AMP/ATP-binding subunit of AMP-activated protein kinase (AMPK), an energy sensor protein kinase that plays a key role in regulating cellular energy metabolism. In response to reduction of intracellular ATP levels, AMPK activates energy-producing pathways and inhibits energy-consuming processes
Gamma non-catalytic subunit mediates binding to amp, adp and atp, leading to activate or inhibit ampk: amp-binding results in allosteric activation of alpha catalytic subunit (prkaa1 or prkaa2) both by inducing phosphorylation and preventing dephosphorylation of catalytic subunits.
