A3QPB9 - IL21_RAT

Protein

Interleukin-21

Gene

Il21

Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at transcript leveli
  1. Functioni

    Cytokine with immunoregulatory activity. May promote the transition between innate and adaptive immunity. Induces the production of IgG1 and IgG3 in B-cells. 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 By similarity. During T-cell mediated immune response may inhibit dendritic cells (DC) activation and maturation By similarity.By similarity
