Glutaredoxin-3

Gene

Glrx3

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Crucial regulator of cellular iron homeostasis and hemoglobin maturation (By similarity). Critical negative regulator of cardiac hypertrophy and a positive inotropic regulator. May play a role in regulating the function of the thioredoxin system. Does not possess any thyoredoxin activity since it lacks the conserved motif that is essential for catalytic activity.By similarity2 Publications

Interactioni

Subunit structurei

Monomer and homodimer; the homodimer is probably linked by 2 2Fe-2S clusters that may serve as a redox sensor. The monomer interacts with other proteins. Interacts (via N-terminus) with PRKCQ/PKC-theta. Interacts with CSRP2 (By similarity). Interacts (via C-terminus) with CSRP3.By similarity1 Publication

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
