Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0011445
UniProt IDP25024
Primary gene name(s)CXCR1
Synonym gene name(s)CMKAR1, IL8RA
Protein nameC-X-C chemokine receptor type 1
Protein functionReceptor 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 locationCell membrane;
Multi-pass membrane protein.
