SULT2A1 (Sulfotransferase Family 2A Member 1): SULT2A1 is a gene that encodes an enzyme from the sulfotransferase family. This enzyme is responsible for sulfating various compounds, including hormones, drugs, and xenobiotics. The sulfation reactions catalyzed by SULT2A1 are crucial for metabolizing and eliminating these substances, playing a key role in the body’s detoxification processes.
