AMP-Activated Protein Kinase Beta

**Semantic type:** Amino Acid, Peptide, or Protein

**Definition:** A family of proteins that function as a regulatory beta subunit for the 5'-AMP-activated protein kinase (AMPK) protein complex. AMPK is a heterotrimeric protein kinase complex that plays a key role in regulating cellular energy metabolism and is comprised of a catalytic alpha subunit and non-catalytic beta and gamma subunits. The beta subunit exists as two isoforms, each is encoded by a separate gene.

**Synonyms:** - 5' AMP-Activated Protein Kinase Beta - 5' Adenosine Monophosphate-Activated Protein Kinase Beta - 5'-AMP-Activated Protein Kinase Beta - 5'-AMP-Activated Protein Kinase Subunit Beta - AMPK Subunit Beta - AMPKb - AMPKbeta
