  • Target

    • Function

      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.
    • Tissue specificity

      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.
    • Sequence similarities

      Contains 1 Sushi (CCP/SCR) domain.
    • Post-translational

      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.
    • Cellular localization

      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.

    Customer reviews and Q&As


    Thank you for your phone call. Unfortunately, I was unable to obtain any more specific information about the immunogen other than that it is the extracellular domain (33-205aa) of mouse IL-15R alpha (Q60819). I hope this helps, please let me know if you need any additional information or assistance.
