• Other karyopherins besides CRM must bind to FG Nups

  2020-01-30

  

  Other karyopherins besides CRM1 must bind to FG-Nups in a similar fashion. However, at an atomic resolution, only the interaction of importin β with isolated FG motifs has been analyzed (Bayliss et al., 2000, Bayliss et al., 2002, Liu and Stewart, 2005). Despite similarities in the FG-binding pocket

• CRF binds to CRF and CRF receptor

  2020-01-30

  

  CRF binds to CRF1 and CRF2 receptor subtypes, triggering downstream cascades and leading to stimulatory G protein (GsP) activation. Once activated, GsP undergoes a structural change provoking the separation of the subunits Gα and Gβγ. The Gα subunit induces the production of the second messenger cAM

  2020-01-30

  

  Our conclusion is in disagreement with that of a recent paper by Park et al. [10], which suggests that nitric oxide (NO) inhibition of VHL recruitment occurs by nitrosylation of the 520 cysteine in HIF-1α, and that SNAP does not directly inhibit hydroxylation of HIF peptide by HPH-2. Although this d

  2020-01-30

  

  RCT pathway plays a critical role in the maintenance of cholesterol homeostasis by facilitating the cholesterol clearance and cholesterol efflux (Levinson & Wagner, 2015). In the process of RCT, ABCA1 and ABCG1 played as crucial regulators in cholesterol efflux (Yasuda et al., 2011). Compared with h

  2020-01-30

  

  Immune modulation by steroid hormones is a rather new aspect of the research on endocrine interactions in lower vertebrates (Harris and Bird, 2000). In the classical view, steroids exert their effects by binding to specific intracellular receptors that function as ligand-activated transcriptional re

  2020-01-29

  

  In SLO-permeabilized human sperm, the AR elicited by calcium, persistently active Arf6 [41] and Rab3A, 8-pCPT-2′-O-Me-cAMP [8], diacylglycerol and a non-hydrolyzable analog [35], is sensitive to the PLC blocker U73122. Furthermore, 8-pCPT-2′-O-Me-cAMP elicits a calcium signal in non-permeabilized sp

  In this study we investigated the role 17-phenyl tinor (pt)-PGE2 on endothelial barrier function and the underlying molecular mechanism in HMVEC-Ls as well as in a murine model of LPS-induced acute pulmonary inflammation. We found that 17-pt-PGE2 concentration-dependently enhanced endothelial barrie

  Although 3DP technologies are convenient for users to manufacture devices automatically, the printing materials are inevitably limited by the manufacturers of 3D printers. Strategies are increasingly being developed to functionalize the raw printing materials or their printed devices with other phys

  2020-01-29

  

  Our research has demonstrated that the absolute bioavailability of oxymatrine, having a similar structure with OSC, was only 6.79±2.52%. About 50% of OSC was converted to its active metabolite SC in vivo; hence, the absolute bioavailability of OSC was speculated to be poor as well [24]. Understandin

• HOIP s ability to build linear Ub

  2020-01-29

  

  HOIP\'s ability to build linear Ub chains arises from a unique domain that follows directly after the RING2 domain, the linear ubiquitin chain-determining domain (LDD) (Fig. 1). Structures have revealed that the LDD is structurally integrated into RING2, creating a single RING2–LDD unit (Fig. 2D) [4

  2020-01-29

  

  Here we uncover a highly diverse superfamily of self-replicating MGEs, dubbed pipolins, which are present in three major bacterial phyla, as well as in mitochondria, and encode divergent PolB carrying TPR1 and TPR2 subdomains. Biochemical characterization of a representative enzyme encoded by a pipo

  Our data show a site-specific interaction of DDR2 with collagen II. This indicates that the DDRs recognise a particular sequence within collagen and not simply the collagenous triple helix per se. This common tertiary structure of all collagens is formed by three α chains, each with a repeating G-X-

  2020-01-29

  

  The crystal structure of the B. subtilis Maf (BSU28050) was published in 2000, and, to date, it represents the only experimental work with a purified Maf protein (Minasov et al., 2000). The structure revealed a structural fold similar to that found in ITPases and YjjX proteins, which are nucleotide

  2020-01-29

  

  A further quandary concerning rediscoveries arises in habitats modified and frequented by humans, where rediscovered species may occur through accidental or deliberate introductions (Metcalf et al., 2007) rather than having persisted despite adverse conditions. Confusion regarding origin could evoke

  2020-01-29

  

  In the intestine, absorbed cholesterol can either be esterified by ACAT2 (Soat2) and packed into chylomicrons, transported back to the intestinal lumen by ABCG5/ABCG8, or it can be transported into HDL by ABCA1. ACAT2 is confined to enterocytes and hepatocytes and esterifies cholesterol for intracel
