IL21 Information: IL21 Protein, IL21 Antibody and IL21 Gene

IL21 Gene family

IL21 Protein

IL21 protein 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. {ECO:0000250, ECO:0000269|PubMed:11081504, ECO:0000269|PubMed:15178704}.
