  2019-09-16

  

  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

  2019-09-16

  

  The Wnt signaling pathway has been demonstrated to be responsible for a variety of biological processes. The three best-characterized Wnt signaling pathways are the canonical Wnt pathway, the noncanonical planar cell polarity pathway, and the noncanonical Wnt/calcium pathway. The canonical Wnt/β-cat

  Conflict statement Introduction Prostate cancer (PCa) is the second most frequently diagnosed cancer and the second leading cause of cancer death in men after lung cancer [1], [2]. The incidence and mortality rate of prostate cancer are significantly higher in developed countries especially th

  2019-09-16

  

  The role of chemokine and AD Chemokines are small cytokine proteins that are involved in various immunological and physiological functions. These proteins can be involved in cell migration and localization during homeostasis and inflammation, and as such, they were named chemokines [80]. Chemokin

  Introduction Our understanding of how ligands interact with G protein coupled receptors is evolving, particularly the recognition that some have the ability to preferentially activate a subset of intracellular signalling cascades – so called pathway biased ligands [1]. Additionally, it is now acc

  Results Discussion Our UbV library was originally designed to develop inhibitors of deubiquitinases (Ernst et al., 2013). Recently, we showed that UbVs could exhibit multiple binding modes and mechanisms to modulate HECT E3 activity (Zhang et al., 2016)—one set occupied the HECT domain E2-bind

  2019-09-12

  

  Cytokines are small secreted proteins that mediate and regulate immunity, inflammation, and hematopoiesis. They are produced in response to an immune stimulus. Cytokines regulate the intensity and duration of the immune response by stimulating or inhibiting the activation, proliferation, and/or diff

  The in vitro cytotoxicity of the prodrugs was assessed in the LS174T human colon cell line (). The results were found to reflect the stability of the prodrugs, with the unstable urea compounds ( and ) giving relatively poor cytotoxicity differentials between prodrugs and parents (i.e., approximately

  Our previous studies have demonstrated that the DDR2 discoidin domain fully contains the binding site(s) for the fibrillar collagens I and II (Leitinger, 2003, Leitinger et al., 2004). The binding site for collagen I was mapped to three spatially adjacent surface loops within the DDR2 discoidin doma

  By using live imaging of an ERK fluorescence resonance energy transfer (FRET) sensor, the authors show that ERK activity propagates in a stepwise manner from the center to the periphery of the tracheal placode. This row-by-row propagation of ERK activity fits a relay model in which each row activate

Understanding the regulation mechanism of radiation sensitivity is still a research hotspot. Increased sensitivity to ionizing radiati

  It has been reported that vernolic VEGFR Tyrosine Kinase Inhibitor II pathway accumulation in transgenic Arabidopsis seeds expressing a Δ12-epoxygenase often resulted in failure of germination and impaired growth and development (Singh et al., 2001). Similar phenomena were also reported for transgen
