  In mice, our EBI2EGFP reporter showed that EBI2 is expressed consistently in naive T helper cells. Already single positive CD4+ thymocytes express EBI2 (not shown). In effector and regulatory T cells in naive mice, the percentage of EBI2 expression was lower (∼40%). Like others (Liu et al., 2011), w

  2021-05-21

  

  How does APC/C recognize its substrates and catalyze their ubiquitylation? How are the outcomes and timing of these activities regulated? These questions have driven a decade of structural studies that begin to explain how APC/C interacts with coactivators, substrates, and E2s, and how these interac

  Acknowledgements The study of RING-type E3s continues to grow extremely rapidly. We regret that it was possible to only cite a fraction of the outstanding primary publications in this field. This work was supported by the National Institute of General Medical Sciences grants R01 GM088055 and R01

  2021-05-21

  

  DNA end processing enzymes The simplest DSB is one that consists of two blunt DNA ends as these termini can be re-joined without processing. However, DSBs induced by ionizing radiation and reactive oxygen species are notorious for producing DNA ends which are non-ligatable (“dirty ends”) and thus

  Common features of TdT, pol μ and pol λ TdT, pol μ and pol λ remain in a closed conformation throughout their catalytic cycle, contrary to pol β [24•, 53, 54•]. One possible explanation for this observation is that they have traded fidelity (which requires open-to-closed transition) for a very ti

  Results To understand how Rad53 functions to maintain replisome integrity, we first analyzed newly synthesized leading- and lagging-strand DNA in wild-type (WT) and rad53-1 mutant cells using BrdU-IP-ssSeq, a method that detects synthesis of both leading and lagging strands (Yu et al., 2014).

  2021-05-21

  

  The preferences for source of FAs for DGAT1 and DGAT2 are related to their membrane topologies, subcellular locations, interactions with other proteins or organelles (discussed in the former section), and their differential expression, substrate specificities, and enzyme kinetics. According to UniPr

  Acknowledgements Introduction Laryngeal cancers are the most frequent cancers of the head and neck region and their occurrence is strongly associated with the exposure to cigarette smoke and the consumption of strong alcohols. Almost all laryngeal cancers are squamous cell carcinomas. Usually

  Introduction Natural killer (NK) cells have an unique ability to directly lyse transformed, virus-infected or stressed cells without prior sensitization or major histocompatibility complex (MHC) class I restriction [1], [2]. They were initially defined and shown to be important effectors of the i

  2021-05-21

  

  Given the importance of cysteine cathepsin inhibitors as putative therapeutic molecules and microbial virulence factors, we chose to investigate whether Yersinia enterocolitica may be a potent producer of such inhibitors. Y. enterocolitica is the most heterogeneous species within the genus Yersinia.

  In a previous study we reported that the systemic administration of the α1-adrenergic receptor antagonist prazosin attenuates the deficit in TMP269 synthesis reward function associated with precipitated nicotine withdrawal (Bruijnzeel et al., 2010). One of the aims of the present experiments was to

  2021-05-21

  

  Carnitine acetyltransferase (CrAT) transesterifies short-chain acyl-CoAs, and is located both in mitochondria and peroxisomes. In yeasts and mammals this protein is the product of a single gene [20,21] and the sorting to different organelles is evolutionary conserved, although the mechanism of diffe

  Only a few studies have examined the effect of prostanoids on cardiac fibroblasts. Therefore, this study examines the effect of PGE2 on cardiac fibroblast proliferation and tests the hypothesis that PGE2 causes cardiac fibroblast proliferation via alterations of Sulforhodamine 101 regulatory molec

  It has been reported that PGE2 increases expression of the survivin mRNA (Baratelli et al. 2005) and promotes the stabilization of the survivin protein in some tumor IFN-gamma, murine recombinant (Krysan et al. 2003). However, it is unclear whether PGE2 affects the expression of survivin mRNA or pr

  In vitro studies suggest that cPLA2α does not show clear preference for the headgroup present at the sn-3 position, although a slight preference for zwitterionic phospholipids such as PC and PE has recently been pointed out [24]. In this regard, mass spectrometry analyses of glycerophospholipid hydr
