Technical Data
Nedd4, WW2 domain
Neuronal precursor cell-expressed developmentally downregulated 4 (Nedd4) is an ~120kD E3 ubiquitin ligase. Nedd4 is involved in regulation of ubitiquin-targeted degradation of proteins. Nedd4 interacts with many different E2 enzymes, including human Ubc4, UbcH5B, UbcH5C, UbcH6 and UbcH7, suggesting it plays a role in multiple E2 ubiquitination pathways. Nedd4 contains a C2 domain and several WW domains, which recognize membrane surfaces and Pro-Tyr motifs, respectively. Nedd4 polyubiquitinates the epithelial sodium channel, and mutations that disrupt association between Nedd4 and the channel lead to Liddle’s syndrome, a hyperaldosteronism-like, hypertension disease.

Suitable for use in Western Blot and Immunohistochemistry. Other applications have not been tested.

Recommended Dilutions:
Western Blot: 1:10,000 detects Nedd4, WW2 domain on 10ug of mouse kidney cytosol. Mouse kidney cytosol lysate was resolved by electrophoresis, transferred to PVDF and probed with N0577-15. Proteins were visualized using an IgG (HRP) goat anti-rabbit and a chemiluminescence detection system.
Immunohistochemistry: Reported to detect Nedd4 in mouse kidney, lung and distal colon sections.
Optimal dilutions to be determined by the researcher.

Recommended Secondary Antibodies:
