  Likewise, the conserved cysteine in the E2 protein is the only residue shown to be essential for the transfer of Ub/Ubl from E2 to the HECT ligases (Dye and Schulman, 2007, Wu et al., 2003). However, all other terminal Ub/Ubl transfer reactions involving E2 enzymes suggest a critical role for the ta

  2020-06-17

  

  The structure of the HOIP RBR–LDD module bound to UbcH5~Ub reveals insights into an activated HOIP component [47]. Contacts between the E2~Ub and the non-cognate RBR module in the crystal suggest how a structure in which the active sites of the E2 and the E3 are in close proximity might look. In thi

  Discussion The regulation of intracellular cholesterol levels is a biological process of vital importance for cellular function and integrity, and involves robust transcriptional and post-transcriptional mechanisms that are sensitive to metabolic feedback control.

  Acknowledgments Introduction Understanding the characteristics of the Amazonian Dark soils “Terras Pretas de Índio” (TPIs) is of ecological importance, because the TPI soils represent a residue-based model for tropical sustainable agriculture (Sombroek et al., 2003, Neves et al., 2003, Cohen-O

  In the present study we investigated the effect of morphine withdrawal on G-protein coupling to opioid and ET receptors in neonatal rats. Morphine-induced G-protein activation was significantly higher in neonatal rats undergoing morphine withdrawal; suggesting enhanced coupling of the receptors to G

  Functional studies revealed that these ESR1 mutations lead to constitutive activity of the ER, meaning that the receptor is active in absence of estrogen, conferring resistance against several endocrine agents. Recent studies reported that the occurrence of ESR1 mutations is rare in ER+ primary brea

  2020-06-16

  

  Intriguingly, one E2 residue may serve as a molecular ‘gate’ to allow the C-terminus of ubiquitin to access the closed E2~Ub conformations favorable for ubiquitin transfer. This residue, Asp87 in UbcH5 family members, resides on one side of the opening that leads to the active site Cys (Fig. 4D). In

  2020-06-16

  

  Cellular immune responses, such as phagocytosis and apoptosis, are very important processes to eradicate the invading pathogens and reduce concomitant host damage. And all of these processes are fine-tuned by the ubiquitin system (Li et al., 2016). Phagocytosis is a major mechanism of cellular immun

  In this study, Oncomine, GEO and TCGA databases were used to analyze the expression of UBE2S gene in HCC and normal liver tissues to determine the relationship between UBE2S expression and prognosis of hepatocellular carcinoma. The potential function of UBE2S in HCC was analyzed by screening UBE2S c

  At the cellular level, TGF-β1 has been involved in the formation of invadosomes (Mandal et al., 2008, Varon et al., 2006). Invadosomes are actin-based structures involved in matrix degradation and cell invasion through metalloproteinases (MMP) activity (Linder et al., 2011). Invadosomes, constitutiv

  Taken together, our results demonstrate that the changes of striatal dopamine release and locomotor activity observed following chronic nicotine treatment and consequent acute withdrawal are mediated by CRF1, but not CRF2. Previous studies have already indicated that blocking CRF1 would prevent some

  Several studies on the collagen receptor DDR1 have revealed a defined collagen signaling pathway that causes cell scattering and cadherin switching. As mentioned earlier, DDR GSK2118436 on collagens are distinct from integrin binding sites; therefore, the same collagen protein can bind to DDR and i

  We neither observed changes in midazolam eCLmet indicative of significant inhibition of CYP3A4/5 during both experiments, despite the in vitro evidence for CYP3A4/5 inhibition (Theile et al., 2017). The observed increase in CYP3A dependent midazolam clearance after chronic ingestion of clementines/c
