The mh1 domain of smad4 was shown to associate physically with ubc9, the ubiquitin carrier protein (e2) conjugating enzyme in sumoylation. In cultured cells, smad4 is modified by sumo-1 at the endogenous level. The sumoylation sites were identified as two evolutionarily conserved lysine residues, lys-113 and lys-159, in the mh1 domain. We found that the mutations at lys-113 and lys-159 did not alter the ability of smad4 to form a complex with smad2 and fast on the mix.2 promoter. Importantly, sumo-1 overexpression enhanced tgf-beta-induced transcriptional responses. These findings identify sumoylation as a unique mechanism to modulate smad4-dependent cellular responses |

Here, we report that the SUMO-E2 conjugating enzyme Ubc9 was identified to interact with ZHX1 by an interaction screen using a yeast two-hybrid system. This interaction was confirmed by co-immunoprecipitation and co-localization assays. Further study showed that ZHX1 is SUMOylated by Ubc9 with SUMO1 at the sites K159, K454, and K626. Furthermore, we demonstrated that the SUMOylation of ZHX1 regulated the stability, ubiquitination and transcriptional activity of ZHX1. The sumoylation of zinc‐fingers and homeoboxes 1 (ZHX1) by ubc9 regulates its stability and transcriptional repression activity. However, in the current work, we demonstrated that ZHX1 was only SUMOylated by SUMO1. |

C/EBPalpha interacts directly with the E2 SUMO-conjugating enzyme Ubc9 and can be SUMOylated in vitro using purified recombinant components. Our results indicate that SUMO modification of SC motifs provides a means to rapidly control higher order interactions among transcription factors and suggests that SUMOylation may be a general mechanism to limit transcriptional synergy. |

One mechanism by which LMP1 regulates cellular activation is through the induction of protein posttranslational modifications. We have now identified a specific target of LMP1-induced sumoylation, interferon regulatory factor 7 (IRF7). We hypothesize that during EBV latency, LMP1 induces the sumoylation of IRF7, limiting its transcriptional activity and modulating the activation of innate immune responses. We recently documented that LMP1 induces a third major protein modification by physically interacting with the SUMO-conjugating enzyme Ubc9 through CTAR3 and inducing the sumoylation of cellular proteins in latently infected cells. we identified that IRF7 is sumoylated at lysine 452. |

In this study, we identified Ubc9 as a host protein that interacts specifically with SARS-CoV N protein. This interaction was verified both in vivo and in vitro. Furthermore, we showed that, in addition to phosphorylation, the N protein was modified by covalent attachment of SUMO to its lysine 62 residue. Evidence provided demonstrated that sumoylation may promote homo-oligomerization of the protein. |

Co-expression of STRA13 and UBC9 led to an increase of the pSTRA13 ubiquitination and subsequent degradation. These data established that UBC9/STRA13 association in cells is of physiological importance, presenting direct proof of UBC9 involvement in the ubiquitin-dependent degradation of pSTRA13. We also checked whether UBC9 is directly involved in pSTRA13 ubiquitination. Taken together, these results strongly suggest that pSTRA13 is targeted for proteolysis by the ubiquitin-dependent proteasome pathway through association with UBC9. |
