XC Chemokine Receptor 1 is a 38kD member of the G-protein coupled receptor 1 family. It binds XCL1/lymphotactin/SCM-1 alpha and XCL2/SCM-1 beta. In addition, human herpes virus 8 (HHV8) encodes two viral chemokines vCCL2/vMIP-II and vCCL3/vMIP-III that function as an antagonist and a highly selective agonist, respectively, for XC Chemokine Receptor 1. XC Chemokine Receptor 1 is expressed on neutrophils, CD8+ T cells , NK cells, CD4+ T cells and B cells. Human XC Chemokine Receptor 1 is a 333aa, 7-transmembrane molecule. It contains a 32aa N-terminus that lacks glycosylation sites and a 42aa C-terminal cytoplasmic tail. Over the extracellular regions used for immunization, human XC Chemokine Receptor 1 shares 62%, 54% and 64% aa identity with canine, mouse and porcine XCR1, respectively.
