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. |
