Target Background

High-affinity receptor for interleukin-15. Can signal both in cis and trans where IL15R from one subset of cells presents IL15 to neighboring IL2RG-expressing cells. In neutrophils, binds and activates kinase SYK in response to IL15 stimulation. In neutrophils, required for IL15-induced phagocytosis in a SYK-dependent manner.
