  2022-09-30

  

  The manner in which various residue side chains are oriented in the active site of HsHxKIV was a driving factor for why glucosamine analogues could not bind, as we previously proposed [16]. These compounds would have difficulty managing access into the active site based on residue P153 in addition t

  2022-09-30

  

  Gap junction channels exhibit different types of gating properties. One alternative mechanism that should be mentioned is loop gating in which the extracellular loop of connexin assumes a configuration to form a narrow pathway for closure of unopposed hemichannels [53] and docked junction channels [

  2022-09-30

  

  The orientation of the immobilized enzyme may affect its activity and stability and therefore the final biocatalyst performance. Since proteins present areas more prone to unfolding in their surface or near to it [36], the immobilization through these areas may improve the final biocatalyst stabilit

  2022-09-30

  

  uPAR promotes cell-associated proteolysis by binding to uPA which locally converts plasminogen into active plasmin [10]. Ligand-engaged uPAR also acts as a potent regulator of cell migration and matrix attachment. Being a membrane receptor, uPAR needs to interact with extracellular matrix (ECM) prot

  2022-09-30

  

  Defining the cooperation between molecular pathways within highly complex biological systems, such as those between immune cell networks and target tissues is certainly a hard task. Recently, there are many investigations in the pathogenesis of renal graft rejection, one of the most evident investig

  2022-09-29

  

  The presence of the H3 receptor in humans was confirmed approximately 25 years ago, and the receptor was successfully cloned in 1999 (Thurmond, 2010). The H3 receptor is unique, as it controls feedback of histamine release, particularly in the central nervous system, where it modulates neurotransmit

  2022-09-29

  

  There have been a few studies investigating the effects of histamine on mast cells but the majority of these has been on rodent and cultured mast cells (Hofstra et al., 2003, Lippert et al., 2004, Jemima et al., 2014). How representative these systems are of primary human cells is a moot point since

  2022-09-29

  

  Several plant-derived molecules such as resveratrol, curcumin, zerumbone, and physalin B have been reported as modulators of Hh/Gli signaling pathway (Hosoya et al., 2008, Mohapatra et al., 2015). Our previous studies have demonstrated that a sesquiterpene lactone and diarylheptanoids from Siegesbec

• HDAC enzymes oppose the effects of

  2022-09-29

  

  HDAC enzymes oppose the effects of HATs by reversing lysine acetylation, an action that restores the positive charge of the lysine thus stabilizing the local chromatin structure. By removing acetyl groups from ε-amino lysines of proteins, HDACs not only alter transcription, but also promote either t

  2022-09-29

  

  In the present study, we focused on a role of the C-terminal segment in GCAP2 using two chimeric proteins, in which the C-terminal segment of GCAP2 was either replaced by the corresponding sequence of recoverin (chimera GR) or transferred into recoverin (chimera RG). We have monitored Ca-dependent c

  2022-09-29

  

  Continuing studies of endocannabinoid ligands at GPR55 reveal that virodhamine (O-arachidonylethanolamine) and AEA can act as a partial agonists at GPR55; at high micromolar concentrations can inhibit β-arrestin recruitment (Sharir et al., 2012). It is likely that there are allosteric as well as ort

  2022-09-28

  

  Heterocysts provide the required microoxic environment for the oxygen-sensitive N2-fixing nitrogenase enzyme complex. This environment is formed during heterocyst development. Developing heterocysts inactivate photosystem II and degrade antenna pigments, thereby decreasing oxygenic photosynthesis (F

  On the basis of their relative Glu transport rates and anion currents, EAATs group into two functionally distinct classes, EAAT1–3 being efficient Glu transporters with small associated macroscopic anion currents and EAAT4–5 low-capacity transporters with predominant anion conductance [18]. The diff

  2022-09-28

  

  The transport of glutamate by EAAT2 from the extracellular fluid into either astrocytes or endothelial cells is an unfavorable and energy-consuming process. This energy is provided by a coupled co-transport of three sodium ions, one proton, and one glutamate molecule in the counter-transport of one
