  • 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.
  • Tissue specificity

    Expressed in heart, spleen, testis and, to a lower extent, in thymus and peripheral blood leukocytes. Weakly expressed in lung, placenta, colon and small intestine.
  • Sequence similarities

    Contains 2 glutaredoxin domains.
    Contains 1 thioredoxin domain.
  • Domain

    The thioredoxin domain lacks the two redox-active cysteines. This strongly suggests that it lacks thioredoxin activity.
  • Cellular localization

    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.
