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