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. This receptor also binds to chemokine (C-X-C motif) ligand 1 (CXCL1/MGSA), a protein with melanoma growth stimulating activity, and has been shown to be a major component required for serum-dependent melanoma cell growth. This receptor mediates neutrophil migration to sites of inflammation. The angiogenic effects of IL8 in intestinal microvascular endothelial cells are found to be mediated by this receptor. Knockout studies in mice suggested that this receptor controls the positioning of oligodendrocyte precursors in developing spinal cord by arresting their migration. This gene, IL8RA, 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. Alternatively spliced variants, encoding the same protein, have been identified. [provided by RefSeq, Nov 2009]
GeneCards Summary for CXCR2 Gene
CXCR2 (C-X-C Motif Chemokine Receptor 2) is a Protein Coding gene. Diseases associated with CXCR2 include Autosomal Recessive Severe Congenital Neutropenia Due To Cxcr2 Deficiency and Neutrophil Migration. Among its related pathways are Innate Immune System and Peptide ligand-binding receptors. Gene Ontology (GO) annotations related to this gene include G protein-coupled receptor activity and C-X-C chemokine receptor activity. An important paralog of this gene is CXCR1.
UniProtKB/Swiss-Prot for CXCR2 Gene
Receptor for interleukin-8 which is a powerful neutrophil chemotactic factor. Binding of IL-8 to the receptor causes activation of neutrophils. This response is mediated via a G-protein that activates a phosphatidylinositol-calcium second messenger system. Binds to IL-8 with high affinity. Also binds with high affinity to CXCL3, GRO/MGSA and NAP-2.
Chemokine CXC receptors (CXCRs) predominantly recognize CXC chemokines. CXC chemokines are distinguished by having four conserved cysteines, with the first two cysteines being separated by a single amino acid. There are six chemokine CXC receptors.
