SANTA CRUZ BIOTECHNOLOGY, INC. www.DataSheet4U.com CD223 (C9B7W): sc-32750 The Power to Question BACKGROUND CD223 (Lymphocyte activation gene-3, LAG-3) is a high affinity MHC class II ligand present on the surface of CD4+/CD8+ T cells and NK cells. CD223 shares homology in structure to CD4 molecules, having four similar extracellular Ig-like domains and structural motifs between D1-D3 and D2-D4 domains. CD223 has a glutamic acid-proline (EP) repetitive sequence found in other functionally distinct mammalian, parasitic, and bacterial proteins that may influence a conserved biological function. CD223+/CD4+/CD8+ T cells can associate with the T cell receptor (TCR) and downregulate TCR signaling in vitro. CD223 inhibits CD4-dependent T cell function via its cytoplasmic domain . CD223 Lys-468 within a conserved "KIEELE" motif is essential for interaction with downstream signaling molecules. APPLICATIONS CD223 (C9B7W) is recommended for detection of CD223 of mouse origin by flow cytometry (1 µg per 1 x 106 cells). Suitable for use as control antibody for CD223 siRNA (m): sc-44548. Molecular Weight of CD223: 70 kDa. DATA REFERENCES 1. Demeure, C.E., et al. 2001.
