NEDD4 Rabbit anti-Human, Mouse, Non-human primate, Rat, Polyclonal, Proteintech

The E3 ubiquitin-protein ligase NEDD4 is a Ubl conjugation pathway protein. It contains one HECT (E6AP-type E3 ubiquitin-protein ligase) domain and four WW domains. It is involved in the pathway leading to the degradation of VEGFR-2/KDFR, independently of its ubiquitin-ligase activity. It acts as a potential proto-oncogene that negatively regulates PTEN via ubiquitination, a paradigm analogous to that of Mdm2 and p53. It is also reported to be involved in the budding of many viruses and is the regulator of epithelial Na+ channels, which lead to arterial hypertension. NEDD4 protein is localized to the sarcolemmal region of muscle fibers. Increase in NEDD4 protein expression leads to unloaded and denervated muscles as well as a decrease in Notch1 expression. Hence it acts as down regulator of Notch-1 gene expression.
