UniProt functional annotation for P25025

UniProt code: P25025.

Organism: Homo sapiens (Human).
Taxonomy: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo.
 
Function: 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.
 
Subcellular location: Cell membrane; Multi-pass membrane protein.
Ptm: Phosphorylated upon ligand binding; which is required for desensitization. {ECO:0000269|PubMed:9079638}.
Ptm: (Microbial infection) Proteolytically cleaved by Staphylococcus aureus staphopain A/SspP. This cleavage inhibits CXCR2-dependent neutrophil activation and chemotaxis. {ECO:0000269|PubMed:22850671}.
Similarity: Belongs to the G-protein coupled receptor 1 family. {ECO:0000255|PROSITE-ProRule:PRU00521}.
