Using a classical chromatographic purification strategy, we identified Nedd4-1 as an E3 ligase that can catalyze mono-ubiquitination of hDCNL1 in a reconstituted ubiquitination system.Taken together, these results suggest a mono-ubiquitination-mediated mechanism that governs nuclear-cytoplasmic trafficking of hDCNL1, |

Gamma2-Adaptin is a putative member of the clathrin adaptor protein family with unknown physiological function. We previously reported that gamma2-adaptin acts as a ubiquitin receptor by virtue of its ubiquitin-interacting motif. Here we demonstrate that this motif mediates a specific physical interaction with the ubiquitin ligase Nedd4 and promotes ubiquitination of gamma2-adaptin. These antibodies clearly recognized the 96 kDa form, thus demonstrating that a fraction of γ2-adaptin is modified by monoubiquitination (Fig. 1C). Thus, binding of γ2-adaptin to Nedd4 is not necessary for its membrane association.Accordingly, one possible function of γ2-adaptin may be to act as an adaptor for Nedd4, recruiting it to membrane compartments for subsequent ubiquitination. |

Only UbcH5 and Related Class I E2s Support Ubiquitination of S5a—UbcH5 belongs to the Class I family of E2s which contains a catalytic core (UBC domain) without a distinct Ub binding domain (38). To test whether other Class I E2s can also support ubiquitination of S5a, we assayed the ubiquitination of S5a with UbcH7 and the E3s, Nedd4, or Parkin. With either of these E3s, UbcH7 supported ubiquitination of S5a (Fig. 8, A and B). In addition, another Class I E2, Ubc4, a close homolog of UbcH5, supported ubiquitination of S5a by the APC, a multimeric Ring finger E3 responsible for cell cycle progression through mitosis (39) (Fig. 8C). Thus, multiple Class I E2s can support ubiquitination of S5a by various types of E3s (Table 1). |

The latent membrane protein (LMP) 2A of Epstein-Barr virus (EBV) is implicated in the maintenance of viral latency and appears to function in part by inhibiting B-cell receptor (BCR) signaling. LMP2A enhances Lyn and Syk ubiquitination in vivo in a fashion that depends on the activity of Nedd4 family members and correlates with destabilization of the Lyn tyrosine kinase. These results suggest that LMP2A serves as a molecular scaffold to recruit both B-cell tyrosine kinases and C2/WW/Hect domain E3 protein-ubiquitin ligases. |

Biologically, NEDD4-1 overexpression sensitizes cancer cells to etoposide-induced apoptosis by reducing SAG levels through targeted degradation.

S5a/Rpn10 is a ubiquitin (Ub)-binding protein that is a subunit of the 26S proteasome but also exists free in the cytosol. It binds poly-Ub chains through its two Ub-interacting motifs (UIMs). We discovered that, unlike typical substrates of Ub ligases (E3s), S5a can be ubiquitinated by all E3s tested including multimeric and monomeric Ring finger E3s (MuRF1, Siah2, Parkin, APC, and SCF(betaTRCP1)), the U-box E3, CHIP, and HECT domain E3s (E6AP and Nedd4) when assayed with UbcH5 or related Ub-conjugating enzymes.The short half-life of S5a presumably is because of the presence of the UIM domain and reflects the ubiquitination of free S5a by many E3s. |

This observation, together with the monoubiquitination of Nedd4-BP1 by the ubiquitin ligase Nedd4 suggests that the NYN domain proteins of eukaryotes are regulated by monoubiquitination. Given the localization of Nedd4-BP1 to punctuate nuclear bodies, it is likely that they are parts of nuclear RNA-processing complexes that are dependent on monoubiquitination for their assembly. |

Ndfip1 is primarily localized in the Golgi apparatus where it recruits Nedd4-2 to mediate the degradation of mature hERG proteins during channel trafficking to the plasma membrane. Although Ndfip2 directs Nedd4-2 to the Golgi apparatus, it also recruits Nedd4-2 to the multivesicular bodies (MVBs), which may impair MVB function and impede the degradation of mature hERG proteins mediated by Nedd4-2. |

Gamma2-Adaptin is a putative member of the clathrin adaptor protein family with unknown physiological function. We previously reported that gamma2-adaptin acts as a ubiquitin receptor by virtue of its ubiquitin-interacting motif. Here we demonstrate that this motif mediates a specific physical interaction with the ubiquitin ligase Nedd4 and promotes ubiquitination of gamma2-adaptin. These antibodies clearly recognized the 96 kDa form, thus demonstrating that a fraction of γ2-adaptin is modified by monoubiquitination (Fig. 1C). Thus, binding of γ2-adaptin to Nedd4 is not necessary for its membrane association.Accordingly, one possible function of γ2-adaptin may be to act as an adaptor for Nedd4, recruiting it to membrane compartments for subsequent ubiquitination. |
