Nedd 4 -2是一种泛素连接酶,以前被证明可以调节上皮Na+通道(ENaC)和其他离子通道和转运蛋白的内吞作用和溶酶体降解。最近使用Nedd 4 -2敲除小鼠特异性地在肾脏或肺上皮中的研究揭示了这种E3泛素连接酶在调节这些组织/器官中的盐和流体运输以及维持身体血压的稳态中的关键作用。有趣的是,Nedd 4 -2的主要靶点在这两个器官中可能不同:在肺中,Nedd 4 -2靶向ENaC,Nedd 4 -2的缺失导致ENaC功能过度和囊性纤维化样肺病,而在肾脏中,Nedd 4 -2除了靶向ENaC外,还靶向Na+/Cl−协同转运蛋白(NCC)。与此雅阁,远端肾单位Nedd 4 -2的缺失导致NCC丰度和功能增加。醛固酮反应性激酶Sgk 1似乎参与肾脏中Nedd 4 -2对NCC的调节,类似于其对ENaC的调节。总的来说,这些新发现强调了Nedd 4 -2在调节上皮盐和液体运输和平衡中的生理重要性。
Nedd4-2 is a ubiquitin ligase previously demonstrated to regulate endocytosis and lysosomal degradation of the epithelial Na+ channel (ENaC) and other ion channels and transporters. Recent studies using Nedd4-2 knockout mice specifically in kidney or lung epithelia has revealed a critical role for this E3 ubiquitin ligase in regulating salt and fluid transport in these tissues/organs and in maintaining homeostasis of body blood pressure. Interestingly, the primary targets for Nedd4-2 may differ in these two organs: in the lung Nedd4-2 targets ENaC, and loss of Nedd4-2 leads to excessive ENaC function and to cystic fibrosis – like lung disease, whereas in the kidney, Nedd4-2 targets the Na+/Cl− cotransporter (NCC) in addition to targeting ENaC. In accord, loss of Nedd4-2 in the distal nephron leads to increased NCC abundance and function. The aldosterone-responsive kinase, Sgk1, appears to be involved in the regulation of NCC by Nedd4-2 in the kidney, similar to its regulation of ENaC. Collectively, these new findings underscore the physiological importance of Nedd4-2 in regulating epithelial salt and fluid transport and balance.
