Dynasore是一种非竞争性的GTP酶抑制剂,IC50值为15 μM[1][2]。
GTP酶(单GTP酶)是水解酶,在GTP的结合和水解中起重要作用。GTP酶参与许多过程,如信号转导、蛋白生物合成、蛋白的细胞膜易位以及细胞内小泡的运输。据报道,dynasore可抑制dynamin1、dynamin2和Drp1的GTP酶活性[3] [4]。
Dynasore是一种有效的GTP酶抑制剂,作用于dynamin1、dynamin2或Drp1上的位点。在HL-1细胞中,dynasore通过抑制动力素的活性,阻断内吞过程[1]。用遗传编码pH敏感的荧光探针synaptopHluorin来研究动力素在表达spH的突触中的作用,结果表明,dynasore通过减少动力素的GTP酶活性,导致正常刺激触发的荧光强度的增加,从而阻断突触内吞作用[4]。Dynasore作为动力素GTP酶活性的抑制剂,可阻断细胞和神经元中动力素依赖的内吞作用[3]。
