靶點詳情

  • 功能:
    Antigen-presenting molecule specialized in displaying microbial pyrimidine-based metabolites to alpha-beta T cell receptors (TCR) on innate-type mucosal-associated invariant T (MAIT) cells. In complex with B2M preferentially presents riboflavin-derived metabolites to semi-invariant TRAV1-2 TCRs on MAIT cells, guiding immune surveillance of the microbial metabolome at mucosal epithelial barriers. Signature pyrimidine-based microbial antigens are generated via non-enzymatic condensation of metabolite intermediates of the riboflavin pathway with by-products arising from other metabolic pathways such as glycolysis. Typical potent antigenic metabolites are 5-(2-oxoethylideneamino)-6-D-ribitylaminouracil (5-OE-RU) and 5-(2-oxopropylideneamino)-6-D-ribitylaminouracil (5-OP-RU), products of condensation of 5-amino-6-D-ribityaminouracil (5-A-RU) with glyoxal or methylglyoxal by-products, respectively. May present microbial antigens to various TRAV1-2-negative MAIT cell subsets, providing for unique recognition of diverse microbes, including pathogens that do not synthesize riboflavin. Upon antigen recognition, elicits rapid innate-type MAIT cell activation to eliminate pathogenic microbes by directly killing infected cells. During T cell development, drives thymic selection and post-thymic terminal differentiation of MAIT cells in a process dependent on commensal microflora. Acts as an immune sensor of cancer cell metabolome. May present a tumor-specific or -associated metabolite essential for cancer cell survival to a pan-cancer TCR consisting of TRAV38.2-DV8*TRAJ31 alpha chain paired with a TRBV25.1*TRBJ2.3 beta chain on a non-MAIT CD8-positive T cell clone (MC.7.G5), triggering T cell-mediated killing of a wide range of cancer cell types.

    13. A novel MR1B isoform probably plays a physiological role complementary to MR1A with respect to mucosal-associated invariant T cells development and/or function. PMID: 23457030
    14. Human thymic MR1-restricted MAIT cells are innate pathogen-reactive effectors that adapt following thymic egress. PMID: 22692454
    15. metabolites of vitamin B represent a class of antigen that are presented by MR1 for MAIT-cell immunosurveillance; as many vitamin biosynthetic pathways are unique to bacteria and yeast, data suggest that MAIT cells use these metabolites to detect microbial infection PMID: 23051753
    16. Mutagenesis of MR1 showed that only two residues, which were centrally positioned and on opposing sides of the antigen-binding cleft of MR1, were essential for MAIT cell activation PMID: 22412157
    17. Taken together these results strongly suggest that MR1 needs to bind proteasome-independent ligands in order to properly reach the cell surface. PMID: 21777569
    18. fact that MR1 seems mainly intracellular might offer clues as to the process, given the precedence in other class I molecules PMID: 21190736
