  Our data furthermore suggest that Ch25h-induced oxysterols could play an important role in modulating the immune cell migration. Mechanistically, we observed impaired trafficking of CD44+CD4+ T cells in mice deficient for Ch25h. CD44+CD4+ T cells lacking EBI2, the receptor of 7α-25OHC, were delayed

  2020-09-18

  

  Taken together, these assays demonstrate that SUMOD positioning is essential for all E3 ligases but dispensable for E2 and S*E2 sumoylation reactions. Thus, we propose SUMOD positioning as a key criterion to describe the enzymatic function of SUMO E3 ligases that distinguishes them from other enhanc

  Deubiquitination, deubiquitinases and cancer Protein deubiquitination is reverse process of ubiquitination and performed by deubiquitinases or deubiquitinating enzymes (DUBs), which help in removal of ubiquitin from target proteins and involve in ubiquitin maturation, recycling and editing (Pfoh

  2020-09-18

  

  If the factors needed for A-NHEJ are not completely defined and the A-NHEJ reaction mechanism nebulous, it is also fair to say that the biological role(s) of A-NHEJ is even more poorly understood. Most of the current interest in A-NHEJ, however, stems from its implicated use in the chromosomal trans

  To understand more clearly how these activities are combined in the heterotrimeric enzyme and to understand more clearly how DNA alkylation might effect DNA helicase activity, we summarize the relevant features of the structure of RecBCD determined in the presence of DNA. The RecB and RecC subunits

  Although DAPK has been implicated in neuronal death in ischemic stroke and neurodegenerative diseases, such as Alzheimer’s disease (Shamloo et al., 2005, Duan et al., 2013), the mechanisms about how DAPK regulates cell death are still elusive. In the present study, we investigated the signal transdu

  The ERRα gene lacks the typical TATA and CAAT boxes, but has multiple consensus Sp1 binding elements in the GC-rich promoter (Shi et al., 1997). Previously, our laboratory has shown that ERRα expression is upregulated in the mouse uterus by estrogen (Shigeta et al., 1997) and recently we identified

  Apoptosis, type I programmed cell death, is considered to be involved in the pathogenesis of various liver diseases, such as autoimmune hepatitis [[5], [6], [7], [8], [9], [10]] and hepatocellular carcinoma [11,12]. Apoptosis is activated by a variety of extrinsic or intrinsic pathways factors. Prev

  Structure of USP7 Schematic representation of the USP7 domain architecture is shown in Fig. 3B. USP7 is a 135 kDa protein that consists of seven domains, including the N-terminal TRAF-like (Tumor necrosis factor Receptor–Associated Factor) domain, followed by the catalytic core domain and the fiv

  Main Text Post-translational modifications by ubiquitin (Ub) and ubiquitin-like proteins (Ubl) regulate a diverse array of cellular and physiological processes including protein degradation, localization, and activation. While ubiquitination has primary responsibility for targeting substrates for p

  Discussion Several DPP-4 inhibitors are currently available for use in the treatment of type 2 diabetes mellitus. Due to the different chemical structures there are marked differences both in the binding kinetics on the target enzyme [10] and also different pathways of elimination [13] exist. In

  [11C]-(+)-PHNO has been described as a full agonist at both D2 and D3 receptors [54,55]. [11C]-(+)-PHNO was initially developed as a PET radiotracer for imaging the high affinity state of the D2 receptor (i.e., highD2) as a means of measuring synaptic dopamine changes in response to pharmacologic ch

  Our finding that one enzyme acts both as a primase and a DNAP poses evolutionary and mechanistic questions. In particular, why do cellular organisms require two enzymes to fulfill de novo DNA synthesis? The inability of cellular replicases to perform as primases might be dictated by the challenges a
