Function
Critical negative regulator of cardiac hypertrophy and a positive inotropic regulator (By similarity). May play a role in regulating the function of the thioredoxin system. Does not posses any thyoredoxin activity since it lacks the conserved motif that is essential for catalytic activity.
Specificity
Natural and recombinant Human Glutaredoxin-3
Subcellular Location
Cytoplasm cell cortex Cytoplasm myofibril sarcomere Z line Under the plasma membrane. After PMA stimulation, GLRX3 and PRKCQ/PKC-theta translocate to a more extended submembrane area. In the Z line, found associated with CSRP3.
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 (via C-terminus) with CSRP3 (By similarity). Interacts with CSRP2.
