Glutaredoxin 1 (human, recombinant)

Glutaredoxin 1 (Grx1) is a thiol-disulfide oxidoreductase and member of the thioredoxin family encoded by GLRX1 with a role in the maintenance of cellular thiol redox homeostasis. It is ubiquitously expressed and localizes to the cytosol, nucleus, and mitochondrial intermembrane space. Grx1 is a dithiol Grx that contains two active site cysteine residues, which catalyze the deglutathionylation of protein disulfides and glutathionylated proteins to regulate redox signal transduction and repair oxidized proteins. Knockdown or overexpression of GLRX1 enhances or reduces, respectively, oxidative stress-induced apoptosis in HEK293T cells. Glrx1-/- mice have increased bronchoalveolar lavage fluid (BALF) macrophage infiltration and lung glutathionylated protein levels induced by cigarette smoke compared with wild-type mice. Grx1 levels are decreased in postmortem brain from patients with Parkinson's disease. Cayman's Glutaredoxin 1 (human, recombinant) can be used for enzyme activity assays.Synonyms: Glrx1, Grx1, Thioltransferase 1, TTF1. Purity: >95% estimated by SDS-PAGE.
