重组人IL-1R2蛋白(C-Fc, HEK293)
/ Recombinant Human IL-1R2 (C-Fc, HEK293); Interleukin-1 receptor type 2
Recombinant Human IL-1R2 (C-Fc, HEK293) 是人源重组蛋白,在HEK293人源细胞中表达,带有C-Fc标签。该蛋白为白细胞介素-1受体2(IL1R2),属于白细胞介素-1受体家族,是一种非信号传导型受体,可竞争性结合IL1B,抑制其活性,通过与IL1RAP形成复合物,减少IL1B与信号受体的结合,从而调节免疫应答,主要在B淋巴细胞、单核细胞、中性粒细胞及内皮细胞中表达。

| 描述 | Interleukin-1 receptor type 2 (IL1R2) belongs to the interleukin-1 receptor family. Two distinct types of IL1 receptors which are able to bind IL1 specifically have been identified, designated as IL1RI (IL1RA) and IL1RII (IL1RB). IL1 receptor type II is a 68 kDa transmembrane protein found on B lymphocytes, neutrophils, monocytes, large granular leukocytes and endothelial cells. IL1R2 is non-signaling receptor forIL1A, IL1B and IL1RN, reduces IL1B activities. IL1R2 serves as a decoy receptor by competetive binding to IL1B and preventing its binding to IL1R1. IL1R2 modulates cellular response through non-signaling association with IL1RAP after binding to IL1B. IL1R2 (membrane and secreted forms) preferentially binds IL1B and poorly IL1A and IL1RN. The secreted IL1R2 recruits secreted IL1RAP with high affinity; this complex formation may be the dominant mechanism for neutralization of IL1B by secreted/soluble receptors. |
