What is the Meaning of Selenoproteins?

Selenoproteins are a unique family of proteins that contain the trace element selenium in the form of the amino acid selenocysteine, which is essential for their biological function. These proteins are critical components of the body's antioxidant defense and regulatory systems, playing vital roles in thyroid hormone metabolism, immune function, and protection against oxidative stress. Deficiencies in selenium can impair the function of these crucial enzymes, impacting overall endocrine health.

What is the Origin of Selenoproteins?

The term is a compound of 'seleno,' referring to the element selenium, and 'proteins,' indicating their biochemical class. This nomenclature immediately identifies their defining characteristic: the incorporation of selenocysteine.

What is the Mechanism of Selenoproteins?

Key selenoproteins, such as the iodothyronine deiodinases, catalyze the activation and inactivation of thyroid hormones by removing iodine atoms, thus precisely regulating thyroid hormone availability in target tissues. Other selenoproteins, like glutathione peroxidases, function as powerful antioxidants, neutralizing reactive oxygen species that could otherwise damage glandular tissue. Their central role in thyroid function and cellular protection highlights the interdependence of micronutrient status and endocrine homeostasis.
