Role of Selenoproteins in Redox Regulation of Signaling and the Antioxidant System: A Review

Antioxidants, 2020
Selenium is a vital trace element present as selenocysteine (Sec) in proteins that are, thus, known as selenoproteins. Humans have 25 selenoproteins, most of which are functionally characterized as oxidoreductases, where the Sec residue plays a catalytic
