IL-21 Protein, Rat

IL-21 Protein, crucial in immune responses and lymphocyte activation, exhibits biased expression in tissues like the thymus and spleen. Predicted to be active in the extracellular space, it serves as a biomarker for periodontal disease and is implicated in conditions like asthma, hepatocellular carcinoma, and systemic lupus erythematosus. IL-21 Protein, Rat is the recombinant rat-derived IL-21 protein, expressed by E. coli , with tag free. The total length of IL-21 Protein, Rat is 122 a.a., with molecular weight of ~14.5 kDa.

IL-21 Protein is predicted to possess interleukin-2 receptor binding activity and is anticipated to be involved in various processes, including lymphocyte activation in immune responses, positive regulation of immune effector processes, and tyrosine phosphorylation of STAT protein. Additionally, IL-21 is predicted to act upstream of or within processes such as positive regulation of cytokine production, positive regulation of lymphocyte activation, and positive regulation of tyrosine phosphorylation of STAT protein. The protein is expected to be located in the extracellular space. IL-21 serves as a biomarker for periodontal disease and is implicated in various human conditions, including asthma, common variable immunodeficiency, hepatocellular carcinoma, and systemic lupus erythematosus. Notably, IL-21 exhibits biased expression in tissues such as the thymus and spleen, indicating its potential role in immune regulation within these organs.
