FunctionReceptor for interleukin-15. Expression of different isoforms may alter or interfere with signal transduction. Isoform 5, isoform 6, isoform 7 and isoform 8 do not bind IL15. Signal transduction involves STAT3, STAT5, STAT6, JAK2 (By similarity) and SYK.
Tissue specificityIsoform 1, isoform 3, isoform 4, isoform 5, isoform 6, isoform 7, isoform 8 and isoform 9 are widely expressed. Expressed in fetal brain with higher expression in the hippocampus and cerebellum than in cortex and thalamus. Higher levels of soluble sIL-15RA form in comparison with membrane-bound forms is present in all brain structures.
Sequence similaritiesContains 1 Sushi (CCP/SCR) domain.
modificationsA soluble form (sIL-15RA) arises from proteolytic shedding of the membrane-anchored receptor. The cleavage involves ADAM17/TACE (By similarity). It also binds IL-15 and thus interferes with IL-15 binding to the membrane receptor.
Phosphorylated by activated SYK.
N-glycosylated and O-glycosylated.
Cellular localizationSecreted > extracellular space; Membrane. Nucleus membrane. Mainly found associated with the nuclear membrane and Endoplasmic reticulum membrane. Golgi apparatus membrane. Cytoplasmic vesicle membrane. Membrane. Isoform 5, isoform 6, isoform 7 and isoform 8 are associated with endoplasmic reticulum, Golgi and cytoplasmic vesicles, but not with the nuclear membrane.

ab91270 staining IL-15RA in normal Human PBMCs by Flow cytometry.
Normal Human PBMCs were isolated, and cultured in standard conditions for 3 hours. Non adherent cells were removed from culture, and remaining cells were stimulated with LPS and IFN-? for 24 hours.
Open/green histogram; stained with 0.25 µg of Purified Mouse IgG2b Isotype Control
Closed/blue histogram; stained with 0.25 µg of ab91270.
Detection utilised Biotin Anti-Mouse IgG and SAv-PE.
Cells in the large scatter population were used for analysis.
