CC   -!- FUNCTION: Cytokine that stimulates the proliferation of T-lymphocytes.
CC       Stimulation by IL15 requires interaction of IL15 with components of the
CC       IL2 receptor, including IL2RB and probably IL2RG but not IL2RA (By
CC       similarity). In neutrophils, stimulates phagocytosis probably by
CC       signaling through the IL15 receptor, composed of the subunits IL15RA,
CC       IL2RB and IL2RG, which results in kinase SYK activation (By
CC       similarity). {ECO:0000250|UniProtKB:P40933}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the IL-15/IL-21 family. {ECO:0000305}.
