Lesson plan
GLRX2
Glutaredoxin 2 (GLRX2) is an enzyme that in humans, is encoded by the GLRX2 gene. GLRX2, also known as GRX2, is a glutaredoxin family protein and a thiol-disulfide oxidoreductase that maintains cellular thiol homeostasis. This gene consists of four exons and three introns, spanned 10 kilobase pairs, and localized to chromosome 1q31.2–31.3. Alternative splicing of GLRX2 leads to three isoforms of Grx2. One isoform, Grx2a, localizes to the mitochondria, is ubiquitously expressed in tissues (e.g. heart, skeletal muscle, kidney, and liver), regulates mitochondrial redox homeostasis, and protects cells against oxidative stress. Isoforms Grx2b and Grx2c, both localized to the nucleus and cytosol, are expressed only in testes and cancer cell lines and facilitate cellular differentiation and transformation, potentially inducing tumor progression.
