General annotation (Comments)

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.

Sequence similarities

Belongs to the G-protein coupled receptor 1 family.
