Background: xCT/SLC7A11

xCT, also called SLC7A11, is the light chain component of the cysteine/glutamate amino acid exchange transporter system Xc (1,2). System Xc is composed of two subunits, the light chain (xCT) and the heavy chain (CD98hc, SLC3A2) and functions by cellular uptake of cysteine in exchange for glutamate in a 1:1 ratio (1,2). The human xCT gene is located on chromosome 4q28.3 and is synthesized as a 12-pass transmembrane protein with both the N- and C-terminals located intracellularly (2, 3). xCT is a 501 amino acids (aa) protein with a theoretical molecular weight of 55.4 kDa (3, 4). xCT expression serves many functional purposes in cells including redox balance, ferroptosis, and chemotherapy or cancer drug resistance (1-3, 5-7). Import of cysteine by xCT plays a role in promoting oxidative stress response as cysteine is a precursor for glutathione synthesis (2, 3, 5-7). Glutathione is a cofactor for ROS-detoxifying enzymes, including glutathione peroxidase (GPX), which help defend from cellular ROS-induced damage (2, 3, 5-7). In addition to its antioxidant role, xCT also utilizes glutathione and GPX to inhibit ferroptosis, which is iron-dependent, non-apoptotic cell-death that occurs with overproduction of lipid hydroperoxides (1-3, 5-7). As cancer cells often experience high oxidative stress, it is understandable that xCT is overexpressed in a variety of cancer types, such as acute myeloid leukemia and breast cancer, and affects cancer growth, invasion, metastasis, and prognosis (1-3, 5-7). xCT expression has also been shown to play a role in glutathione-mediated drug resistance during cancer treatment (1,5,7). However, studies have shown that xCT knockdown results in increased tumor cell death, highlighting its suitability as a druggable target (1,5,7). Specifically, the xCT inhibitors Sulfasalazine, an approved anti-inflammatory drug, and Erastin, a small molecule inhibitor, are potential therapeutic modalities for treating a variety of cancers when used in combination with radiotherapy or immunotherapy (1-3, 5-7).

FAQs for xCT Antibody (23H6) - BSA Free

Showing  1 - 1 of 1 FAQ Showing All

  • Q: Do you have a slc7a11 antibody that is conjugated, reacts to mouse, works with cell surface staining, does not need permeabilization?

    A: SLC7A11 or xCT antibody NB300-318AF594 targets a cytoplasmic region of the protein, so it should work without permeabilization. However, the data does say it was permeabilized with saponin, so we cannot say for certain if it will work without permeabilization.
