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. Surprisingly, the same four Lys residues on S5a, Lys-74, Lys-122, Lys-262, and Lys-365 were ubiquitinated by MuRF1 and E6AP (Fig. 10). Two additional Lys residues (Lys-126 and -135) were ubiquitinated by E6AP. |

E6AP and E6 together provide the E3-ubiquitin protein ligase activity in the transfer of ubiquitin to p53. In vitro studies have shown that E6AP can form a high energy thiolester bond with ubiquitin and, in the presence of E6, transfer ubiquitin to p53. In this study we have addressed the role of E6AP in vivo in the degradation of p53. |

An in vivo ubiquitination assay was done to reveal that E6AP promoted the ubiquitination of TSC2 independent of HPV16 E6. We further found that TSC2 bound E6AP in the presence as well as in the absence of HPV16 E6. The binding regions on E6AP and TSC2 have been identified as amino acid (aa) 260-316, aa 428-500 and aa 1-175, aa 1251-1807, respectively. Taken together, degradation of TSC2 is mediated by E6AP ubiquitin ligase. |

Here we report that the functionality of ALDH1A2, the rate-limiting enzyme of retinoic acid (RA) synthesis, is negatively regulated by UBE3A in a ubiquitylation-dependent manner. |

Overexpression of E6-AP results in degradation of TH1 in a dose-dependent manner, whereas knock-down of endogenous E6-AP elevates the TH1 protein level. |

Additionally, the expression of a dominant-negative E6AP mutant (C833A) in cells inhibited the E6-induced degradation of E6TP1. These findings demonstrate that the E6-induced decrease in the levels of E6TP1 protein involves the E6AP-mediated ubiquitination followed by proteasome-dependent degradation. |
