What's a GeneRIF?

Crystal structure of Grx6 in complex with a glutathione-coordinated [2Fe-2S] cluster has been presented.
Title: Crystal structure of yeast monothiol glutaredoxin Grx6 in complex with a glutathione-coordinated [2Fe-2S] cluster.
A specific function influenced by Grx6 activity is the homeostasis of intracellular calcium. Grx6-deficient mutants have reduced levels of calcium in the ER lumen, whereas accumulation occurs at the cytosol from extracellular sources.
Title: Altered intracellular calcium homeostasis and endoplasmic reticulum redox state in Saccharomyces cerevisiae cells lacking Grx6 glutaredoxin.
Compared to the classic dithiol glutaredoxin Grx1, Grx6 has a lower glutathione disulfide reductase activity but a higher glutathione S-transferase activity.
Title: Structural and biochemical characterization of yeast monothiol glutaredoxin Grx6.
Grx6 and Grx7 do not play a general role in the oxidative folding of proteins in the early secretory pathway but rather counteract the oxidation of specific thiol groups in substrate proteins.
Title: A novel group of glutaredoxins in the cis-Golgi critical for oxidative stress resistance.
GRX6 could be responsible for the regulation of the sulfhydryl oxidative state at the oxidant conditions of the early secretory pathway vesicles.
Title: Saccharomyces cerevisiae Grx6 and Grx7 are monothiol glutaredoxins associated with the early secretory pathway.
S. pombe cells harboring plasmid pFGRX6 containing the Grx6 gene had about 1.3-fold elevated Grx activity in the exponential phase, and grew better than the control cells under some stressful conditions.
Title: Expression, characterization and regulation of a Saccharomyces cerevisiae monothiol glutaredoxin (Grx6) gene in Schizosaccharomyces pombe.
