项目摘要

The aim of this study was to identify functionally important proteincomplexes regulating AQP water channels, CLC chloride channels and Na-Cl cotransporter(NCC), by focusing on the naturally occurring mutations of these genes. We found that thebinding of tropomyosin 5b to phosphorylated AQP2 was necessary for AQP2's apical sortingby vasopressin. We also found a novel phosphorylation cascade (WNK-OSR1/SPAK-NCC)in the kidney that is important for blood pressure regulation.
本研究的目的是通过关注这些基因的自然发生突变,识别调节 AQP 水通道、CLC 氯离子通道和 Na-Cl 协同转运蛋白 (NCC) 的功能上重要的蛋白质复合物。我们发现原肌球蛋白5b与磷酸化的AQP2的结合对于AQP2通过加压素的顶端分选是必需的。我们还在肾脏中发现了一种新的磷酸化级联(WNK-OSR1/SPAK-NCC),这对于血压调节很重要。
