Definition / general
  • Member of AP2 transcription factor family, which consists of five different yet closely related 50-kDa isoforms
  • Also called adapter protein 2 beta, TFAP2b (transcription factor AP 2 beta), Activating enhancer-binding protein-2β
Pathophysiology
  • Regulates expression of many downstream genes, orchestrating a variety of cell processes, particularly cell induction, differentiation, survival, and proliferation and apoptosis within various developmental contexts (Mol Cancer 2014;13:89, Ann Thorac Surg 2011;92:1044)
  • Assembly protein associated with clathrin-coated vesicles, involved in endocytosis and Golgi processing (Genomics 1995;30:94)
  • Involved in monoaminergic transmission, likely due to a regulatory effect on monoamine oxidase type A and serotonin transporter (Brain Res 2009;1305 Suppl:S20)
