Previous GeneCards Identifiers for IL21 Gene
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]
GeneCards Summary for IL21 Gene
IL21 (Interleukin 21) is a Protein Coding gene. Diseases associated with IL21 include Immunodeficiency, Common Variable, 11 and Inflammatory Bowel Disease 25, Early Onset, Autosomal Recessive. Among its related pathways are IL27-mediated signaling events and IgA-Producing B Cells in the Intestine. GO annotations related to this gene include cytokine activity and interleukin-2 receptor binding.
UniProtKB/Swiss-Prot for IL21 Gene
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.
