| Tissue Specificity | Widely expressed. |
| Post Translational Modifications | N-glycosylated and O-glycosylated. A soluble form (sIL-15RA) arises from proteolytic shedding of the membrane-anchored receptor. It also binds IL15 and thus interferes with IL15 binding to the membrane receptor. |
| Function | 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. |
