Cystine/glutamate transporter is an antiporter that in humans is encoded by the SLC7A11 gene. The SLC7A11 gene codes for a sodium-independent cystine-glutamate antiporter that is chloride dependent, known as system Xc- or xCT. It regulates synaptic activity by stimulating extrasynaptic receptors and performs nonvesicular glut… WebNov 9, 2024 · SLC7A11 is a cell transmembrane protein composing the light chain of system xc−, transporting extracellular cystine into cells for cysteine production and GSH biosynthesis. SLC7A11 is a critical gateway for redox homeostasis by maintaining the cellular levels of GSH that counter cellular oxidative stress and suppress ferroptosis. …
WebApr 25, 2024 · SLC7A11 promotes cystine uptake and glutathione biosynthesis, resulting in protection from oxidative stress and ferroptotic cell death. Recent studies have unexpectedly revealed that SLC7A11 also plays critical roles in glutamine metabolism and regulates the glucose and glutamine dependency of cancer cells. WebApr 3, 2024 · Most cellular cysteine is acquired through the system x C – antiporter, which exchanges extracellular, oxidized cysteine (cystine) for intracellular glutamate. Yet, germline deletion of the system x C – gene, Slc7a11, is well tolerated in unstressed mice , which suggests that normal cells have low basal cystine import requirements. We ...
WebMar 1, 2024 · We also find that mTORC1 signaling promotes glutathione synthesis through ATF4 and its specific regulation of the cystine transporter SLC7A11. Thus, ATF4 is an anabolic effector of mTORC1 signaling, necessary for both its canonical regulation of protein synthesis and its induced synthesis of glutathione, the most abundant antioxidant in cells. WebSystem Xc − is composed of the light-chain SLC7A11 (xCT) and the heavy-chain SLC3A2 (CD98hc or 4F2hc) and its functions are as raw materials for the synthesis of glutathione (GSH). 18 As its main functional subunit, SLC7A11 encodes a cystine transporter also known as xCT, which is highly specific to cystine and glutamic acid (Glu ...
