Gene Information

human ... IL15(3600)

General description

The protein encoded by this gene is a cytokine that regulates T and natural killer cell activation and proliferation. This cytokine and interleukine 2 share many biological activities. They are found to bind common hematopoietin receptor subunits, and may compete for the same receptor, and thus negatively regulate each other′s activity. The number of CD8+ memory cells is shown to be controlled by a balance between this cytokine and IL2. This cytokine induces the activation of JAK kinases, as well as the phosphorylation and activation of transcription activators STAT3, STAT5, and STAT6. Studies of the mouse counterpart suggested that this cytokine may increase the expression of apoptosis inhibitor BCL2L1/BCL-x(L), possibly through the transcription activation activity of STAT6, and thus prevent apoptosis. Two alternatively spliced transcript variants of this gene encoding the same protein have been reported. (provided by RefSeq)

Biochem/physiol Actions

Interleukin-15 (IL-15) stimulates the proliferation of T lymphocytes and shares many biological properties with IL-2. It exerts its biological activities primarily on T cells. It is also essential in the development, survival and activation of NK cells. On binding to its receptor, IL-15 is indirectly involved in activating proto-oncogenes. Increased expression of IL-15 has been implicated with rheumatoid arthritis, inflammatory bowel disease, multiple sclerosis and diseases affiliated with retroviruses like human immunodeficiency virus (HIV) and human T-lymphotropic virus-1 (HTLV-I).
