FOXA2 (Forkhead Box A2): FOXA2 is a transcription factor that plays a critical role in the development and function of multiple tissues, including the liver, pancreas, and lungs. It regulates genes involved in metabolism, development, and cell differentiation. In the pancreas, FOXA2 is essential for the formation and proper function of insulin-producing beta cells, helping maintain glucose balance by controlling genes related to insulin secretion and glucose metabolism.
