IL-21R Protein, Rat (HEK293, Fc)

IL-21R Protein, a receptor for interleukin-21, is a type I cytokine receptor. It forms a heterodimer with the common gamma subunit and associates with Janus kinase 1 (JAK1). These interactions are pivotal for transducing the cellular responses initiated by interleukin-21, regulating immune processes and inflammatory pathways. IL-21R Protein, Rat (HEK293, Fc) is the recombinant rat-derived IL-21R protein, expressed by HEK293 , with C-mFc labeled tag.

Interleukin 21 receptor (IL-21R), a receptor for interleukin-21, is a type I cytokine receptor. It forms a heterodimer with the common gamma subunit and associates with Janus kinase 1 (JAK1). Through this interaction, the receptor facilitates the signaling cascade initiated by interleukin-21, a cytokine with diverse immunoregulatory functions. The formation of the IL-21R heterodimer and its association with JAK1 are pivotal steps in transducing the cellular responses triggered by interleukin-21, contributing to the regulation of immune processes and inflammatory pathways. IL-21R is highly expressed in hematological malignancies and enhances the aggressiveness of follicular lymphoma. IL-21R results in the pathogenesis of leukemia and large cell lymphoma through activation of the JAK/STAT signaling pathway. The knockdown of IL-21R markedly suppressed GC cell proliferation and invasion, and IL-21R expression was further validated to be negatively regulated by miR-125a-3p (miR-125a). Moreover, it reduces the growth and invasion of NSCLC cells via inhibiting Wnt/β‑catenin signaling and PD‑L1 expression^[1][2].
