Background: XCR1

XCR1, also known as GPR5 and lymphotactin/SCM-1 (single cysteine motif 1) receptor, is a 38 kDa member of the G-protein coupled receptor 1 family. It binds XCL1/lymphotactin/SCM-1 alpha and XCL2/SCM-1 beta. In addition, human herpesvirus 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 XCR1. XCR1 is expressed on neutrophils, CD8⁺ T cells, NK cells, CD4⁺ T cells and B cells. Human XCR1 is a 333 amino acid (aa), 7-transmembrane molecule. It contains a 32 aa N-terminus that lacks glycosylation sites and a 42 aa C-terminal cytoplasmic tail. Over the extracellular regions used for immunization, human XCR1 shares 62%, 54% and 64% aa identity with canine, mouse and porcine XCR1, respectively.
