Human Gene CXCR1 (ENST00000295683.3) from GENCODE V44
  Description: Homo sapiens C-X-C motif chemokine receptor 1 (CXCR1), mRNA. (from RefSeq NM_000634)
RefSeq Summary (NM_000634): 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.

  ID: CXCR1_HUMAN
DESCRIPTION: RecName: Full=C-X-C chemokine receptor type 1; Short=CXC-R1; Short=CXCR-1; AltName: Full=CDw128a; AltName: Full=High affinity interleukin-8 receptor A; Short=IL-8R A; AltName: Full=IL-8 receptor type 1; AltName: CD_antigen=CD181;
FUNCTION: Receptor to interleukin-8, which is a powerful neutrophils chemotactic factor. Binding of IL-8 to the receptor causes activation of neutrophils. This response is mediated via a G-protein that activate a phosphatidylinositol-calcium second messenger system. This receptor binds to IL-8 with a high affinity and to MGSA (GRO) with a low affinity.
SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
SIMILARITY: Belongs to the G-protein coupled receptor 1 family.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
