IL-21 Rabbit Polyclonal Antibody

This gene encodes a member of the common-gamma chain family of cytokines with immunoregulatory activity. 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. [provided by RefSeq, Dec 2011], function:Cytokine with immunoregulatory activity. 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.
