IL-36 alpha/IL-1F6 蛋白, Human (153a.a)

IL-36 alpha (IL-1F6), a subform of IL-36 family, belongs to IL-1 superfamily. IL-36 alpha mediates inflammatory response. IL-36 alpha binds to IL-36R and activates NF-κB and MAPK signaling pathways, but the activation requires N-terminal cleavage by neutrophil granule-derived proteases^[1]. IL-36 alpha also binds to IL-1Rrp2 and recruit IL-1RAcP. IL-36 alpha activats the MAPK, Erk1/2 and JNK through IL-36R/IL-1RAcP^[2]. IL-36 alpha/IL-1F6 Protein, Human (153a.a) is a recombinant human IL-36 alpha (K6-F158) without any tag, which is produced in E. coli.

IL-36α是IL-36家族的一个亚型，属于IL-1超家族。IL-36 α 在单核细胞、T/B 淋巴细胞、脾脏、骨髓扁桃体、淋巴结和皮肤中表达^[2]。IL-36 α 在受损肾脏中表达上调。IL-36 α 与肾脏病变、肝细胞癌以及一些炎症/免疫性疾病（包括结肠炎和牛皮癣）的发生有关^[3]。
IL-36 α 在不同物种中存在差异。人 IL-36 α 与小鼠的氨基酸序列同一性<55%。
IL-36α与IL-36R结合并激活NF-κB和MAPK信号通路，从而介导炎症反应。但激活需要中性粒细胞颗粒衍生的蛋白酶（例如组织蛋白酶 G、弹性蛋白酶和蛋白酶-3^[1]）进行 N 末端裂解。IL-36 α 还可以结合 IL-1Rrp2 并募集 IL-1RAcP。IL-36 α 通过 IL-36R/IL-1RAcP^[2] 激活 MAPK、Erk1/2 和 JNK。
IL-36 α是一种促炎因子。IL-36 α 通过激活 NF-κB 和 MAPK 信号通路介导炎症反应^[1]。

IL-36 alpha (human) (10 ng/mL, 48 h) stimulates the production of TNF-α and IL-1β in HCECs^[4].
IL-36 alpha (human) (500 ng/mL, 48 h) induces maturation of human MDDCs^[5].
IL-36 alpha (human) inhibits proliferation, migration, and invasion of both OV2008 and SKOV-3 cells^[6].
