Research Abstract

Nedd4L has been paid attention for its unique ubiquitinating properties that does an important working to cuticle sodium channel (ENaC) in the tubular epithelial cell and the post-transcriptional modification so far. Clarification and study results of the urinary tubular sodium re-absorption mechanism, and the role of Nedd4L in cardio-renal relationship is examined and the research announcement is done.
