Official Full Name chemokine (C-X-C motif) receptor 1
Background Interleukin 8 receptor, alpha is a chemokine receptor. IL8RA is its human gene. IL8RA has also been designated CD181 (cluster of differentiation 181), and CXCR1. CXCR1 is now the IUPHAR Committee on Receptor Nomenclature and Drug Classification recommended name. The protein encoded by this gene is a member of the G-protein-coupled receptor family. This protein is a receptor for interleukin 8 (IL8). It binds to IL8 with high affinity, and transduces the signal through a G-protein activated second messenger system. Knockout studies in mice suggested that this protein inhibits embryonic oligodendrocyte precursor migration in developing spinal cord. This gene, IL8RB, a gene encoding another high affinity IL8 receptor, as well as IL8RBP, a pseudogene of IL8RB, form a gene cluster in a region mapped to chromosome 2q33-q36.
