  2019-07-31

  

  Each of these substrate receptors belongs to a multigene family with tens, if not hundreds of members in plants, and with in part overlapping and in part differential substrate specificities [4]. The complexity of the system is nicely illustrated by the F-box protein and auxin receptor TRANSPORT IN

  This review focuses on the atomic basis of CRM1-mediated nuclear export. There are now 27 crystal structures of CRM1 in the Protein Data Bank (PDB) (www.rcsb.org) [64]. Collectively, this large body of work explains various aspects of CRM1 function. Here we summarize the structure–function studies t

  Our work raises the question of how a mechanism for control of developmental potency based on TEs might have evolved. Active TEs are under acute surveillance by cellular pathways that minimize transposition, including by Kap1 (Rowe et al., 2010). In part because of this, and in part because of a los

  2019-07-30

  

  In mammals, neutrophil elastase is a trypsin-like serine protease stored in the azurophilic granules of naïve neutrophils [15], [16]. The catalytic activity of neutrophil elastase relies on a His57–Asp102–Ser195 triad (chymotrypsin numbering system) that functions by transfer of electrons from the c

  Discussion The N-terminal domain of DDRs has long been recognized as a member of the DS superfamily (Johnson et al., 1993, Karn et al., 1993), and its role in collagen binding is understood in atomic detail (Carafoli et al., 2009, Ichikawa et al., 2007). Our crystal structure shows that the secon

  2019-07-30

  

  WNV, a member of the genus Flavivirus within the family Flaviviridae, was first isolated in 1937 from a febrile woman in the West Nile region of Uganda (Brinton, 2002). Until 1999, WNV was mainly confined to Southern Europe, the Middle East, Africa, West and Central Asia, Indonesia and Australia. In

  In all available E2:E3 structures, the RING-type domain binds the E2 on a surface that is remote from the active site Cys (and therefore from the ubiquitin thioester) (Fig. 2). The non-contiguous E3-binding and active sites on the E2 imply that the role played by a RING to facilitate ubiquitin trans

• The Inhibitor of APoptosis IAP

  2019-07-30

  

  The Inhibitor of APoptosis (IAP) proteins were first identified as gene products of baculovirus that inhibited apoptosis of infected insect Angiotensin Fragment 1-7 acetate (Clem et al., 1991, Crook et al., 1993). Subsequently, the mammalian IAP family was identified (Rothe et al., 1995, Uren et al.

  The modification of proteins with the small 76-amino Pyridoxine HCl protein ubiquitin (Ub) plays a central role in many key cellular processes. Ubiquitylation of a target protein requires the concerted action of a cascade of three enzymes (Figure 1). The ubiquitin-activating enzyme (E1) catalyzes t

  The TELI results of DNA damage responses to CAA and SO then informed our choice of bacterial strains in subsequent experiments. We investigated E. coli cellular survival in response to CAA and SO exposure by determining the sensitivity of a number of E. coli strains, each possessing single or multip

  Methods To study electrostatic substrate channeling, we employed two methodologies, Brownian dynamics and a continuum model based on the Smoluchowski theory. Whereas Brownian dynamics simulations are useful for tracking the motion of individual particles, the continuum model is convenient for cal

  A surprising second functional effect was found in culture experiments. Inclusion of LTD4 reduced the frequency of Fas receptor (CD95) expression. Once again, this effect, although modest, was reversed by a cysLT1 receptor antagonist. The biologic significance of this effect or its mechanism remaine

  As small non-coding RNAs, microRNAs (miRNAs) can control gene expression at the post-transcriptional level by binding to the 3′-untranslated regions (3′-UTR) of messenger RNAs (mRNA) [15], [16]. miRNAs have been anticipated to regulate virtually all cellular mechanisms [17] and to play an important
