General description

Research area: Cell Signaling

Thioredoxin from Escherichia coli is a monomeric, globular protein. It has a central β-sheet surrounded by α-helices.

Application

Thioredoxin from Escherichia coli has been used in thioredoxin reductase assay, peroxidase-coupled thioredoxin system assay and peroxiredoxin assay. It has also been used to study its effects on photoreceptor death in a mouse model of retinitis pigmentosa (RP) and its potential to modify retinal oxidative stress, glial changes, and vascular changes during the progression of the disease.

Biochem/physiol Actions

Thioredoxin from Escherichia coli catalyzes REDOX reactions and has a role in various biological processes. It modulates the structure and activity of many proteins. The enzyme thioredoxin reductase catalyzes the reduction of thioredoxin. Thioredoxin also has a role in oxidative stress response.Thioredoxin, known as both adult T cell leukemia-derived factor (ADF) and a cellular redox enzyme, functions as a cytokine or chemokine, facilitating cell-to-cell communication. Additionally, it plays a role in regulating cell growth and apoptosis.
Mediates the reduction of disulfide bonds in proteins.

In holothuroids, oocyte maturation is stopped in ovaries at the prophase I stage of meiosis. In natural conditions, the blockage is removed during the spawning by an unknown mechanism. When oocytes are isolated by dissection, the meiotic release can be
