功能Receptor 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.
组织特异性Isoform 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.
序列相似性Contains 1 Sushi (CCP/SCR) domain.
翻译后修饰A 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.
细胞定位Secreted > 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 IL15RA 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.
