The encoded protein plays a role in both the innate and adaptive immune responses by inducing the differentiation, proliferation and activity of multiple target cells including macrophages, natural killer cells, B cells and cytotoxic T cells. Dysregulation of this gene plays a role in multiple immune-mediated diseases including lupus, psoriasis and chronic inflammatory diseases. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

May promote the transition between innate and adaptive immunity. Induces the production of IgG(1) and IgG(3) in B-cells (By similarity). May play a role in proliferation and maturation of natural killer (NK) cells in synergy with IL15. May regulate proliferation of mature B- and T-cells in response to activating stimuli. In synergy with IL15 and IL18 stimulates interferon gamma production in T-cells and NK cells. During T-cell mediated immune response may inhibit dendritic cells (DC) activation and maturation.,similarity:Belongs to the IL-15\/IL-21 family.,tissue specificity:Expressed in activated CD4-positive T-cells but not in CD8-positive T-cells, B-cells, or monocytes.,\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSpecies:\u003c\/b\u003e Human;Mouse\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eRange:\u003c\/b\u003e WB;ELISA\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eProtein:\u003c\/b\u003e Interleukin-21\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDA:\u003c\/b\u003e 18kD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Upingbio","offers":[{"title":"100UL","offer_id":50691392995608,"sku":"YP-Ab-15935-100UL","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/images_05af08a3-b4d6-49b4-bcc8-3cc50d99a235.png?v=1758628552","url":"https:\/\/danabiosci.com\/products\/yp-ab-15935-100ul","provider":"Dana Bioscience","version":"1.0","type":"link"}
