1. Membrane Transporter/Ion Channel
  2. Calmodulin
  3. KS 501

KS 501 是一种强效且选择性的钙调蛋白 (calmodulin) 抑制剂。KS 501 可抑制钙调蛋白激酶 I 和 II 的活化,但对环磷酸腺苷 (cAMP) 敏感激酶的影响较小。KS 501 的抑制作用并非直接作用于酶本身,而是通过干扰钙调蛋白的活化来实现的。KS 501 可用于白血病的研究。

生物活性

KS 501 is a potent and selective calmodulin inhibitor. KS 501 inhibits the activation of calmodulin kinase I and II, but has less effect against cyclic adenosine 3’,5’-monophosphate (cyclic AMP)-sensitive kinase. KS 501 inhibits the enzyme through interfering with calmodulin activation rather than through a direct effect on the enzyme. KS 501 can be used for the study of leukemia[1].

体外研究
(In Vitro)

KS 501 (0-100 μM) 以浓度依赖的方式抑制钙调蛋白敏感的磷酸二酯酶活性 (IC50 = 0.8 μM)[1]
KS 501 (0.25-2 μM) 对磷酸二酯酶活性的抑制作用随着钙调蛋白浓度的增加而逐渐减弱[1]
KS 501 (10-40 μM) 在 40 μM 浓度下抑制钙调蛋白依赖的突触蛋白 I 磷酸化,而 10 μM 浓度下对基础活性无抑制作用,反而略有刺激作用[1]
KS 501 (10-40 μM) 抑制突触蛋白 I 在位点 1(钙调蛋白激酶 I 的底物)以及位点 2 和 3(钙调蛋白激酶 II 的底物)的磷酸化[1]
KS 501 (10-40 μM) 仅部分抑制突触素 I 对 cAMP 敏感性蛋白激酶 (PKA) 的磷酸化[1]
KS 501 (0-120 μM) 抑制 L1210/S 细胞的增殖 (IC50 = 80 μM)[1]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
