The ICOS protein contains an extracellular IgV-like domain, a transmembrane domain, and an intracellular domain with a YMFM motif (1-2). ICOS is primarily expressed on activated CD4 and CD8 T cells (1). Upon binding to its ligand, ICOS potentiates the T cell response to antigen through activation of the PI3K signaling pathway (3). In addition to enhancing T cell activation and proliferation, ICOS plays an important role in the regulation of T follicular helper cells (4). Research studies suggest that ICOS is a potential therapeutic target, and could serve as a prognostic biomarker for neoplastic therapy involving CTLA-4 blockade (5-7).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nActivation-inducible lymphocyte immunomediatory molecule; Ailim; CCLP; CD278; CD28 and CTLA-4-like protein; CD28-related protein 1; CH29-120A16.4; CRP-1; ICOS; inducible T cell co-stimulator; Inducible T-cell costimulator; Ly115; OTTMUSP00000002206; OTTMUSP00000002207\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: M R\nSENSITIVITY: Endogenous\nMW (kDa): 22-35\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46800110321833,"sku":"67223T","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-67223t","provider":"Iright","version":"1.0","type":"link"}
