GRX2/YDR513W Summary Help

Standard Name GRX2 1
Systematic Name YDR513W
Alias TTR1 2
Feature Type ORF, Verified
Description Cytoplasmic glutaredoxin; thioltransferase, glutathione-dependent disulfide oxidoreductase involved in maintaining redox state of target proteins, also exhibits glutathione peroxidase activity, expression induced in response to stress; GRX2 has two in-frame start codons resulting in a shorter isoform that is retained in the cytosol and a longer form translocated to the mitochondrial matrix; GRX2 has a paralog, GRX1, that arose from the whole genome duplication (1, 3, 4, 5, 6, 7, 8, 9)
