GO curators for mouse genes have assigned the following annotations to the gene product of Il21. (This text reflects annotations as of Wednesday, January 23, 2013.) Summary from NCBI RefSeq
[Summary is not available for the mouse gene. This summary is for the human ortholog.] 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.
