双孔隙通道(TPC)

2021-09-14566

双孔通道(TPC)是位于细胞内体上的钙通道。由第二信使NAADP和磷脂磷脂磷脂酰肌醇3,5-二磷酸,PtdIns(3,5)P2)激活,孔隙主要传导Ca2+和Na+。已经证明,它们在埃博拉病毒感染中起着关键作用,并可能作为埃博拉病毒和其他丝状病毒的抗病毒研究提供研究靶点。在内质体膜中,它们负责埃博拉病毒的进入。

Measuring Two Pore Channels

Two Pore Channels can be measured using automated patch clamp when expressed in cell lines, in lysosomes, or using the Orbit instruments when they are recombinantly expressed in bilayers.
