SLC7A11 (Solute Carrier Family 7 Member 11): SLC7A11 is a crucial part of the xCT transporter system, responsible for exchanging extracellular cystine with intracellular glutamate. This exchange is essential for maintaining intracellular glutathione levels, which protect cells from oxidative stress. Overexpression of SLC7A11 has been associated with increased survival of cancer cells under oxidative conditions, making it a significant target in cancer therapy research.
