EBF2 is a transcription factor that regulates adipocyte development and thermogenesis through multiple mechanisms. In brown adipose tissue (BAT), EBF2 functions as part of the core thermogenic gene activation machinery 1, working cooperatively with other transcriptional regulators to control uncoupling protein 1 (UCP1)-dependent thermogenesis 2. EBF2 stability is regulated by the deubiquitinating enzyme USP2; USP2-mediated EBF2 stabilization promotes BAT thermogenesis and protects against obesity 3. Beyond adipose tissue, EBF2 acts as a transcriptional co-regulator with histone methyltransferase KMT2D to suppress pancreatic cancer progression by upregulating the tumor suppressor KLLN 4. Genetically, EBF2 variants are associated with epicardial and pericardial adiposity, contributing to cardiovascular disease risk 5, and EBF2 polymorphisms show significant association with Kawasaki disease in Korean populations 6. In osteosarcoma, miR-204-5p suppresses the oncogenic effects of EBF2 by targeting its mRNA stability, with EBF2 promoting cancer cell migration and survival 7. EBF2 variants also associate with diabetic nephropathy susceptibility 8. Thus, EBF2 has pleiotropic functions spanning metabolic, immune, and oncogenic pathways.
