CC -!- FUNCTION: Receptor for interleukin-8 which is a powerful neutrophil
CC chemotactic factor. Binding of IL-8 to the receptor causes activation
CC of neutrophils. This response is mediated via a G-protein that
CC activates a phosphatidylinositol-calcium second messenger system. Binds
CC to IL-8 with high affinity. Also binds with high affinity to CXCL3,
CC GRO/MGSA and NAP-2. {ECO:0000250|UniProtKB:P25025}.
CC -!- SUBUNIT: Interacts with IL8. Interacts with GNAI2.
CC {ECO:0000250|UniProtKB:P25025}.
CC -!- SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
CC -!- PTM: Phosphorylated upon ligand binding; which is required for
CC desensitization. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the G-protein coupled receptor 1 family.
CC {ECO:0000255|PROSITE-ProRule:PRU00521}.
