GMP OSM 蛋白, Human (His)

OSM protein is a multifunctional growth regulator with dual functions of inhibiting tumor cell lines and stimulating the proliferation of AIDS-KS cells. It coordinates the production of cytokines, including IL-6, G-CSF, and GM-CSF, and binds to type I and type II OSM receptors, forming heterodimers with LIFR/IL6ST and OSMR/IL6ST, respectively. GMP OSM Protein, Human (His) is the recombinant human-derived OSM protein, expressed by E. coli , with N-6*His labeled tag. The total length of GMP OSM Protein, Human (His) is 196 a.a., with molecular weight of ~28.0 kDa.

GMP OSM 蛋白是一种多功能生长调节剂，对多种肿瘤细胞系的增殖具有双重抑制作用，对 AIDS-KS 细胞增殖具有刺激作用。值得注意的是，OSM 协调细胞因子产生的调节，包括内皮细胞的 IL-6、G-CSF 和 GM-CSF。这种多方面的生长调节剂既与 I 型 OSM 受体结合，形成由 LIFR 和 IL6ST 组成的异二聚体，又与 II 型 OSM 受体结合，形成由 OSMR 和 IL6ST 组成的异二聚体。除了其抗增殖和增殖作用之外，OSM 在胎儿肝细胞的成熟中发挥着至关重要的作用，对肝脏发育和再生做出了重大贡献。
