Protein

Thioredoxin H1

Gene

TRX1

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

Thiol-disulfide oxidoreductase involved in the redox regulation of a number of cytosolic enzymes. Activates the cytosolic malate dehydrogenase (MDH) probably by reducing an interchain disulfid bond of the inactive MDH homodimer. Possesses insulin disulfide bonds reducing activity.1 Publication
