A CD4-like member of the Ig superfamily, LAG3 contains an extracellular IgV and three IgC domains, a transmembrane domain, and a short cytoplasmic region (1). LAG3 is primarily expressed by activated CD4 T cells, CD8 T cells, Tregs, and NK cells, where it's activated by MHC Class II molecules, its only known ligand. While it was initially shown to activate Treg cells (2), LAG3 can also inhibit CD8 T cells (3,4). LAG3 is often co-expressed with PD-1 on the surface of tumor infiltrating lymphocytes, where the two proteins act independently to contribute to tumor-mediated immune suppression (4,5). Blockade of LAG3 is a promising strategy for neoplastic intervention (6).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nActivation-induced cytidine deaminase-linked autoimmunity protein; Aida; CD223; LAG; LAG-3; Lag3; Ly6; Ly66; Lymphocyte activation gene 3 protein; lymphocyte-activation gene 3; OTTMUSP00000029126; Secreted lymphocyte activation gene 3 protein; sLAG-3\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: M\nSENSITIVITY: Endogenous\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46800519168169,"sku":"72276S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-72276s","provider":"Iright","version":"1.0","type":"link"}
