Stromelysin-1/MMP-3 蛋白, Human (HEK293, His)

The Stromelysin-1/MMP-3 protein is a multifunctional metalloprotease that degrades a variety of extracellular matrix components and activates molecules such as growth factors, plasminogen, and MMP9. It is released into the ECM and is activated through the plasmin cascade. Stromelysin-1/MMP-3 Protein, Human (HEK293, His) is the recombinant human-derived Stromelysin-1/MMP-3 protein, expressed by HEK293 , with C-6*His labeled tag. The total length of Stromelysin-1/MMP-3 Protein, Human (HEK293, His) is 460 a.a., with molecular weight of ~60 kDa.

Stromelysin-1/MMP-3 是一种金属蛋白酶，具有广泛的底物特异性，能够降解细胞外基质 (ECM) 的各种成分，例如纤连蛋白、层粘连蛋白、明胶（I、III、IV 和 V 型）、胶原蛋白（ III、IV、X 和 IX) 和软骨蛋白聚糖。这种酶在激活不同分子中发挥着关键作用，包括生长因子、纤溶酶原或其他基质金属蛋白酶（如 MMP9）。释放到 ECM 后，无活性的酶原通过纤溶酶级联信号通路进行激活。Stromelysin-1/MMP-3 也在细胞内发挥作用，正如在多巴胺能神经元中观察到的那样，在应激过程中，它被丝氨酸蛋白酶 HTRA2 激活，通过介导小胶质细胞激活和 α-突触核蛋白/SNCA 裂解，导致多巴胺神经元变性。此外，这种金属蛋白酶在免疫反应中发挥作用，并对多种病毒表现出抗病毒活性，包括水泡性口炎病毒、甲型流感病毒 (H1N1) 和人类疱疹病毒 1。从机制上讲，它在病毒感染时从细胞质转位到细胞核中调节 NF-kappa-B 活性。

Measured by its ability to cleave the fluorogenic peptide substrate, Mca-RPKPVE-Nval-WRK(Dnp)-NH2. The specific activity is 3134.18 pmol/min/µg, as measured under the described conditions.
