Interleukin 21, also known as IL21, is a human gene.[1]

The protein encoded by this gene, Interleukin 21, a cytokine that has potent regulatory effects on cells of the immune system, including natural killer (NK) cells and cytotoxic T cells that can destroy virally infected or cancerous cells.[2][3] This cytokine induces cell division/proliferation in its target cells. IL-21 elicits its effects on immune cells by interacting with a cell surface receptor known as the interleukin 21 receptor, IL-21R, that is expressed in bone marrow cells and various lymphocytes.
