Enzymes

Enzyme Details
1. Thioredoxin reductase 1, cytoplasmic
General function:
Involved in oxidoreductase activity
Specific function:
Isoform 1 may possess glutaredoxin activity as well as thioredoxin reductase activity and induces actin and tubulin polymerization, leading to formation of cell membrane protrusions. Isoform 4 enhances the transcriptional activity of estrogen receptors alpha and beta while isoform 5 enhances the transcriptional activity of the beta receptor only. Isoform 5 also mediates cell death induced by a combination of interferon-beta and retinoic acid.
Gene Name:
TXNRD1
Uniprot ID:
Q16881
Molecular weight:
70905.58
Reactions
NADPH + Hydrogen Ion + Methylselenic acid → NADP + Water + Methaneselenoldetails
Enzyme Details
2. Thioredoxin reductase 2, mitochondrial
General function:
Involved in oxidoreductase activity
Specific function:
Maintains thioredoxin in a reduced state. Implicated in the defenses against oxidative stress. May play a role in redox-regulated cell signaling.
Gene Name:
TXNRD2
Uniprot ID:
Q9NNW7
Molecular weight:

3. Thioredoxin reductase 3
General function:
Involved in oxidoreductase activity
Specific function:
Displays thioredoxin reductase, glutaredoxin and glutathione reductase activities. Catalyzes disulfide bond isomerization. Promotes disulfide bond formation between GPX4 and various sperm proteins and may play a role in sperm maturation by promoting formation of sperm structural components (By similarity).
Gene Name:
