The 9.5 MDa human pyruvate dehydrogenase complex (PDC) utilizes the specific dihydrolipoamide dehydrogenase (E3) binding protein (E3BP) to tether the essential E3 component to the 60-meric core of the complex. Here, we report crystal structures of the binding domain (E3BD) of human E3BP alone and in complex with human E3 at 1.6 angstroms and 2.2 angstroms, respectively. The latter structure sho...

Purpose: The initial development of conditionally replicative adenoviruses (CRAds) for cancer treatment has aimed at achieving selective replication in and killing of malignant cells. Other aspects such as the potentiation of the cytolytic capacity have also been investigated but still require new endeavors. As an extension of our prior work, we analyzed the effect of the E3 region, which inclu...

Although several studies have been reported on the synthesis of steroids in the fetus, the metabolism and conjugation of estrogens in the fetus is not completely known. In this study serum levels of estetrol (E4), estetrol glucosiduronate (E4-G), estriol (E3) and estriol-16-glucosiduronate (E3-16-G) were measured by R.I.A. in maternal peripheral vein blood (MPV), umbilical artery blood (UA) and...

BACKGROUND The aim of this study was to investigate whether the anisotropy parameters are helpful in the detection and discrimination of breast cancers, and to determine its value in predicting the risk of cancers. MATERIAL AND METHODS There were 56 patients with 56 lesions (34 malignant, 22 benign) included in the study. DTI was performed in every patient and apparent diffusion coefficient (AD...

The vaccinia virus (VACV) E3 protein is essential for virulence and has antiapoptotic activity and the ability to impair the host innate immune response. Here we demonstrate that E3 interacts with SUMO1 through a small ubiquitin-like modifier (SUMO)-interacting motif (SIM). SIM integrity is required for maintaining the stability of the viral protein and for the covalent conjugation of E3 to SUM...

RanBP2/Nup358 is an essential protein with roles in nuclear transport and mitosis, and is one of the few known SUMO E3 ligases. However, why RanBP2 functions in vivo has been unclear: throughout the cell cycle it stably interacts with RanGAP1*SUMO1 and Ubc9, whose binding sites overlap with the E3 ligase region. Here we show that cellular RanBP2 is quantitatively associated with RanGAP1, indica...

The E3 transcription unit of human adenoviruses (Ads) encodes immunomodulatory proteins. Interestingly, the size and composition of the E3 region differs considerably among Ad species, suggesting that distinct sets of immunomodulatory E3 proteins may influence their interaction with the human host and the disease pattern. However, to date, only common immune evasion functions of species C E3 pr...
