Gene Information

human ... IL21(59067)

IL21 (interleukin 21) is a member of the γ-chain type I cytokine family, and a four-α-helix bundle pleiotropic cytokine. This gene is localized to human chromosome 4q26–q27. Although, it is predominantly produced by T follicular helper (TFH) and T helper-17 (TH17) cells, it is also produced by CD4+ T cells, neutrophils and natural killer cells. Under certain conditions, it is also produced by CD8+ T cells. Recombinant human IL-21 is a 15.0 kDa protein consisting of 132 amino acid residues.
