Glutaredoxin(GRX), also known as thioltransferase, is member of the thiol-disulfide oxidoreductase family. Glutraredoxin catalyzes the reversible reduction of protein-glutathionyl mixed disulfides to free sulfhydryl groups though a monothiol mechanism. Glutaredoxin-3 (Grx3/PICOT) is an essential protein involved in the regulation of signal transduction, for instance during immune cell activation and development of cardiac hypertrophy, presumably in response to redox signals. And it has been shown to interact with PRKCQ. Recombinant human Glutaredoxin-3, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques. Synonyms: Thioredoxin-like protein 2, GLRX3, PICOT, TXNL2, GRX3, glutaredoxin 4, bA500G10.4, GLRX4, GRX4, thioredoxin-like 2, thioredoxin-like 2, glutaredoxin 3,. NCBI no.: NP_006532
