TEF (Thyrotrophic Embryonic Factor): TEF is a member of the PAR bZIP (proline and acidic amino acid-rich basic leucine zipper) transcription factor family. It is involved in circadian rhythm regulation and plays a role in the expression of clock-controlled genes. TEF is important for maintaining the circadian rhythm in physiological processes, including metabolism and hormone secretion. Dysregulation of TEF can impact circadian rhythm-related disorders and metabolic diseases, highlighting its significance in the synchronization of biological processes with the environmental light-dark cycle....
