CC -!- FUNCTION: Non-catalytic subunit of AMP-activated protein kinase (AMPK),
CC an energy sensor protein kinase that plays a key role in regulating
CC cellular energy metabolism. In response to reduction of intracellular
CC ATP levels, AMPK activates energy-producing pathways and inhibits
CC energy-consuming processes: inhibits protein, carbohydrate and lipid
CC biosynthesis, as well as cell growth and proliferation. AMPK acts via
CC direct phosphorylation of metabolic enzymes, and by longer-term effects
CC via phosphorylation of transcription regulators. Also acts as a
CC regulator of cellular polarity by remodeling the actin cytoskeleton;
CC probably by indirectly activating myosin. Beta non-catalytic subunit
CC acts as a scaffold on which the AMPK complex assembles, via its C-
CC terminus that bridges alpha (PRKAA1 or PRKAA2) and gamma subunits
CC (PRKAG1, PRKAG2 or PRKAG3). {ECO:0000256|ARBA:ARBA00025180}.
CC -!- SUBUNIT: AMPK is a heterotrimer of an alpha catalytic subunit (PRKAA1
CC or PRKAA2), a beta (PRKAB1 or PRKAB2) and a gamma non-catalytic
CC subunits (PRKAG1, PRKAG2 or PRKAG3). Interacts with FNIP1 and FNIP2.
CC {ECO:0000256|ARBA:ARBA00025878}.
CC -!- SIMILARITY: Belongs to the 5'-AMP-activated protein kinase beta subunit
CC family. {ECO:0000256|ARBA:ARBA00010926}.
