一般說明
基因IL-1RA（白细胞介素-1受体拮抗剂）定位于人染色体2q上。 它属于IL-1（白细胞介素1）蛋白家族。 编码的蛋白质具有TIR（Toll/IL-1受体）结构域。 IL-1RA由角膜上皮细胞、单核细胞、嗜中性粒细胞、巨噬细胞和成纤维细胞产生。 它是一种天然存在的炎症抑制蛋白。 重组人IL-1RA是由153个氨基酸残基组成的17.2kDa蛋白质。
Research Area: IMMUNO AND CKS
The interleukin-1 receptor antagonist (IL-1Ra) is part of the IL-1 family and binds to IL-1 receptors without triggering any intracellular response. IL-1Ra, produced by hepatic cells, exhibits characteristics of an acute phase protein. Endogenous IL-1Ra is generated in various experimental animal models of disease, as well as in human autoimmune and chronic inflammatory conditions.

應用
IL-1Ra human has been used as an IL1 antagonist to block the signaling from the IL1 receptor and verify that IL1 signaling is responsible for invasiveness in CD133-expressing cells. It has also been used as a control in sandwich enzyme-linked immunosorbent assay (ELISA) to measure protein levels.
生化／生理作用
白细胞介素-1受体拮抗剂（IL-1RA）可通过竞争性阻断与其I型和II型受体的结合来抑制IL-1α（白细胞介素1 α）和IL-1β （白细胞介素1 β）的活性。 在治疗上，IL-1RA可以帮助治疗败血症、类风湿性关节炎、慢性髓性白血病、哮喘、牛皮癣和炎性肠病。 在HIV-1（人免疫缺陷病毒1）感染的树突细胞中观察到IL-1RA的低表达。
The interleukin-1 receptor antagonist (IL-1Ra) functions as a specific and selective competitive inhibitor of IL-1R1, binding to the receptor with high affinity.
