The PD-1 protein contains an extracellular Ig V domain, a transmembrane domain, and a cytoplasmic tail that includes an immunoreceptor tyrosine-based inhibitory motif (ITIM) and an immunoreceptor tyrosine-based switch motif (ITSM). PD-1 is activated by the cell surface ligands PD-L1 and PD-L2 (4). Upon activation, PD-1 ITIM and ITSM phosphorylation leads to the recruitment of the protein tyrosine phosphatases SHP-1 and SHP-2, which suppress TCR signaling (5-7). In addition to activated T cells, PD-1 is expressed in activated B cells and monocytes, although its function in these cell types has not been fully characterized (8). The PD-1 pathway plays an important role in immune tolerance (3); however, research studies show that cancer cells often adopt this pathway to escape immune surveillance (9). Consequently, blockade of PD-1 and its ligands is proving to be a sound strategy for neoplastic intervention (10).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nCD279; hPD-1; hPD-l; hSLE1; PD-1; PD1; PDCD1; programmed cell death 1; programmed cell death 1 protein; Programmed cell death protein 1; Protein PD-1; SLEB2; systemic lupus erythematosus susceptibility 2\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H\nSENSITIVITY: Endogenous\nSource\/Isotype: Mouse IgG1","brand":"CST","offers":[{"title":"Default Title","offer_id":46800330948777,"sku":"48338S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-48338s","provider":"Iright","version":"1.0","type":"link"}
