GLRX3 (Glutaredoxin 3): GLRX3 is a protein belonging to the glutaredoxin family that helps maintain the cell’s redox balance by catalyzing the reversible oxidation and reduction of protein disulfide bonds. This function is essential for protecting cells from oxidative stress, which can cause cellular damage and contribute to conditions such as cancer, cardiovascular disease, and neurodegenerative disorders. GLRX3 also influences key cellular signaling pathways sensitive to redox changes, underscoring its vital role in cellular health and stress responses.
