    SUBCELLULAR LOCALIZATION     plasma membrane
    basic FUNCTION
  • acting as a receptor for chemokines SCYC1 and SCYC2
  • transducing a signal by increasing the intracellular calcium ions level
  • acting as a rhodopsin-like receptor
  • XCL1 and XCR1 are constitutively expressed in the thymus and regulate the thymic establishment of self-tolerance and the generation of regulatory T cells
  • role of XCR1 and its Ligand XCL1 in Antigen Cross-Presentation byhuman dendritic cells
  • emerges as the first surface marker characterizing a dendritic cell lineage potentially in the human
    • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS inflammation
    PATHWAY
    metabolism
    signaling signal transduction
    a component
  • XCL1-XCR1 axis plays an important role in dendritic-cell-mediated cytotoxic immune response
  • XCL1-XCR1 axis thus emerges as an integral component in the development of efficient cytotoxic immunity
    • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • certain dendritic cells subsets should be chemotactic towards Natural killer or activated CD8(+) T cells through XCR1
