  • N-terminus binds to the N-loop and third beta-strand of CCL21 chemokine domain
  • seven transmembrane segments (7TM) receptor

    SUBCELLULAR LOCALIZATION     plasma membrane
    basic FUNCTION
  • probable mediator of EBV effects on B lymphocytes or of normal lymphocyte functions
  • activating B and T lymphocytes
  • controls migration of memory T cells to inflamed tissues and stimulate dendritic cell maturation
  • promotes metastasis by preventing anoikis in cancer cells
  • is the essential adhesion signal required for the targeting of leukaemic T-cells into the CNS
  • CCR7 and CCL21 contribute to the migratory capacity of the dendritic cells
  • directly activates GATA2 transcription, which is an important gene for the maintenance of hematopoietic stem cells
  • CCR7 mediates entry into the lymph nodes and S1PR1 signaling controls their subsequent exit
  • CCR7-independent transport of skin self-Ags occurs in the dermis
  • eosinophils express CCR7 and have multipotent responses to the known ligands of CCR7
  • playing no appreciable role in trafficking of central memory CD4 T cells to lymph nodes
    text inflammatory response
    signaling signal transduction
    a component
    small molecule
  • receptor for the MIP-3-beta chemokine (CCL19)
  • high affinity for CCL21
  • chemokine receptor involved in the migration of neutrophils to the lymph nodes
  • CCR7 was found to interact directly with TOPI
  • CCL21 chemokine recruits normal immune cells and metastasizing tumor cells to lymph nodes through activation of the G protein-coupled receptor CCR7
  • after binding to CCL19, CCR7 signaling leads to increased expression and phosphorylation of MAPK7 and up-regulation of KLF2, which results in S1PR1 expression and a migration of T lymphocytes
  • contribution of CCR7 to STAP2-dependent enhancement of BCR-ABL-mediated cell growth in Ba/F3 cells
  • RGS1 desensitizes the chemokine receptors CCR7 and CXCR4 that are critical to the localization of T and B cells in lymphoid organs
