basic FUNCTION	key enzyme in the regulation of the intracellular redox environment
	mitochondrial TXNRD3 is much less dependent upon the use of selenocysteine (Sec) for the reduction of small molecules, as TXNRD1
	role of TXNRD1 gene in modulating physical decline at extreme ages, further supporting the investigation of thioredoxin pathway in relation to the quality of human aging.
	suppresses anabolic metabolism and adipogenesis by inhibition of intracellular signaling pathways downstream of insulin stimulation
	is an essential selenium-containing enzyme involved in detoxification of reactive oxygen species (ROS) and redox signaling
	overexpression of the cytosolic form, TXNRD1, did not produce a lifespan extension in males flies
	selenium-dependent oxidoreductases TXNRD1 and TXNRD2 should be considered as key components of signaling pathways that control cell differentiation and cellular stress responses
	is a key regulator involved in the ferroptosis of chronic myeloid leukemia (CML) cells induced by cysteine depletion
	TXNRD1 is an essential component of the thioredoxin system, a major disulfide reducing system that modulates multiple cellular processes such as antioxidant response, apoptosis, and cell proliferation
