产品介绍
Okadaic acid ammonium salt 是一种海洋毒素，是蛋白质磷酸酶(PP)的抑制剂，包括PP1(IC50=15-50 nM)、PP2A(IC50=0.1-0.3 nM)、PP3(IC50=3.7-4 nM)、PP4(IC50=0.1 nM) 和PP5(IC50=3.5 nM)，其中对 PP2A 的亲和力最显著，但不抑制 PP2C。Okadaic acid ammonium salt 通过抑制 PP 增加了多种蛋白的磷酸化，并具有肿瘤启动子的作用。Okadaic acid ammonium salt 诱导 tau 蛋白磷酸化。
生物活性

Okadaic acid ammonium salt, a marine toxin, is an inhibitor ofprotein phosphatases (PP). Okadaic acid ammonium salt has a significantly higher affinity forPP2A(IC50=0.1-0.3 nM), and inhibitsPP1(IC50=15-50 nM),PP3(IC50=3.7-4 nM),PP4(IC50=0.1 nM),PP5(IC50=3.5 nM), but does not inhibit PP2C. Okadaic acid ammonium salt increases of phosphorylation of a number of proteins by inhibiting PP, and acts as a tumor promoter. Okadaic acid ammonium salt induces tau phosphorylation[1][2].
