Gene Symbol IL15
Protein Name interleukin 15
Synonyms IL-15;
Species Homo sapiens
Ensembl Protein ENSP00000296545
InnateDB Gene IDBG-39028 (IL15)
Protein Structure
UniProt Annotation
Function Cytokine that stimulates the proliferation of T- lymphocytes. Stimulation by IL-15 requires interaction of IL-15 with components of IL-2R, including IL-2R beta and probably IL-2R gamma but not IL-2R alpha.
Subcellular Localization Isoform IL15-S48AA: Secreted.Isoform IL15-S21AA: Cytoplasm. Nucleus. Note=IL15-S21AA is not secreted, but rather is stored intracellularly, appearing in the nucleus and cytoplasmic components.
Disease Associations
Tissue Specificity Most abundant in placenta and skeletal muscle. It is also detected in the heart, lung, liver and kidney. IL15- S21AA is preferentially expressed in tissues such as testis and thymus.
