生化/生理作用
2,3-丁二酮一肟是ATP-敏感K+和Ca2+通道抑制剂。
DRK1是一种延迟整流 (Kv2.1)克隆K+ 通道,来自大鼠大脑,和基于蛋白质激酶磷酸化有相同位点,可能与官能化调节磷酸化有关。 2,3-丁二酮一肟(BDM)化学性地从许多蛋白质中移除磷酸基团。在蟾蜍卵母细胞DRK1 CRNA表达后研究它对于DRK1通道的行为。在双电极电压钳实验中,将2,3-丁二酮一肟用于浴槽抑制DRK1电流(ki = 16.6 mM, H = 0.96)速度快,而且可逆,时间过程和浴槽内溶液改变时间过程相似。DRK1电流在所有电位被抑制;电流活化,钝化和失活的时间过程没有被2,3-丁二酮一肟影响。在内面向外式膜片钳实验中,在缺少再磷酸化底物时,在细胞表面使用2,3-丁二酮一肟同样也会快速地抑制通道活性,而且可逆 (ki = 10.7 mM, H = 1.01)。这些结果和磷酸酶效应不一致,因为磷酸酶效应应该在无细胞,无ATP的膜片中不可逆的。相反,结果显示2,3-丁二酮一肟能够从膜里或膜外直接抑制DRK1通道。

Despite recent advances in our understanding of the mechanism for ventricular fibrillation (VF), important electrophysiological aspects of the development of VF still are poorly defined. It has been suggested that the onset of VF involves the disintegration of a single

Actin and myosin are components of plasmodesmata, the cytoplasmic channels between plant cells, but their role in regulating these channels is unclear. Here, we investigated the role of myosin in regulating plasmodesmata in a well-studied, simple system comprising single filaments
