GLRX3 (Glutaredoxin 3): GLRX3 is a protein from 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 crucial for protecting cells from oxidative stress, which can cause cellular damage and contribute to diseases such as cancer, cardiovascular disease, and neurodegenerative disorders. GLRX3 also affects key cellular signaling pathways that respond to redox changes, highlighting its essential role in cellular health and stress responses.
