ALERT: This system is being upgraded on Tuesday December 12. It will not be available
for use for several hours that day while the upgrade is in progress. Deposits to DukeSpace
will be disabled on Monday December 11, so no new items are to be added to the repository
while the upgrade is in progress. Everything should be back to normal by the end of
day, December 12.

29 mammalian genomes reveal novel exaptations of mobile elements for likely regulatory functions in the human genome.
(PloS one, 2012-01)Recent research supports the view that changes in gene regulation, as opposed to changes in the genes themselves, play a significant role in morphological evolution. Gene regulation is largely dependent on transcription ... -
A C-terminal motif found in the beta2-adrenergic receptor, P2Y1 receptor and cystic fibrosis transmembrane conductance regulator determines binding to the Na+/H+ exchanger regulatory factor family of PDZ proteins.
(Proc Natl Acad Sci U S A, 1998-07-21)The Na+/H+ exchanger regulatory factor (NHERF) binds to the tail of the beta2-adrenergic receptor and plays a role in adrenergic regulation of Na+/H+ exchange. NHERF contains two PDZ domains, the first of which is required ... -
A complex intronic enhancer regulates expression of the CFTR gene by direct interaction with the promoter.
(J Cell Mol Med, 2009-04)Genes can maintain spatiotemporal expression patterns by long-range interactions between cis-acting elements. The cystic fibrosis transmembrane conductance regulator gene (CFTR) is expressed primarily in epithelial cells. ... -
A functional analysis of the spacer of V(D)J recombination signal sequences.
(PLoS Biol, 2003-10)During lymphocyte development, V(D)J recombination assembles antigen receptor genes from component V, D, and J gene segments. These gene segments are flanked by a recombination signal sequence (RSS), which serves as the ... -
A Lysine Residue Essential for Geminivirus Replication Also Controls Nuclear Localization of the Tomato Yellow Leaf Curl Virus Rep Protein.
(Journal of virology, 2019-05)Geminiviruses are single-stranded DNA (ssDNA) viruses that infect a wide range of plants. To promote viral replication, geminiviruses manipulate the host cell cycle. The viral protein Rep is essential to reprogram the cell ... -
A novel human endogenous retroviral protein inhibits cell-cell fusion.
(Scientific reports, 2013-01)While common in viral infections and neoplasia, spontaneous cell-cell fusion, or syncytialization, is quite restricted in healthy tissues. Such fusion is essential to human placental development, where interactions between ... -
A nucleosome-guided map of transcription factor binding sites in yeast.
(PLoS Comput Biol, 2007-11)Finding functional DNA binding sites of transcription factors (TFs) throughout the genome is a crucial step in understanding transcriptional regulation. Unfortunately, these binding sites are typically short and degenerate, ... -
ACE-inhibition increases podocyte number in experimental glomerular disease independent of proliferation.
(Journal of the renin-angiotensin-aldosterone system : JRAAS, 2015-06)<h4>Objective</h4>The objective of this article is to test the effects of angiotensin-converting enzyme (ACE)-inhibition on glomerular epithelial cell number in an inducible experimental model of focal segmental ... -
Afatinib induces apoptosis in NSCLC without EGFR mutation through Elk-1-mediated suppression of CIP2A.
(Oncotarget, 2015-02)Afatinib has anti-tumor effect in non-small cell lung carcinoma (NSCLC) with epidermal growth factor receptor (EGFR) mutation. We found afatinib can also induce apoptosis in NSCLC cells without EGFR mutation through CIP2A ... -
ARFGAP1 plays a central role in coupling COPI cargo sorting with vesicle formation.
(J Cell Biol, 2005-01-17)Examining how key components of coat protein I (COPI) transport participate in cargo sorting, we find that, instead of ADP ribosylation factor 1 (ARF1), its GTPase-activating protein (GAP) plays a direct role in promoting ... -
Association with endoplasmic reticulum promotes proteasomal degradation of GADD34 protein.
(The Journal of biological chemistry, 2011-06)Stress-induced endogenous and ectopically expressed GADD34 proteins were present both in the cytoplasm and in membranes, with their membrane association showing similar biochemical properties. Deletion of N-terminal sequences ... -
beta-arrestin-1 competitively inhibits insulin-induced ubiquitination and degradation of insulin receptor substrate 1.
(Mol Cell Biol, 2004-10)beta-arrestin-1 is an adaptor protein that mediates agonist-dependent internalization and desensitization of G-protein-coupled receptors (GPCRs) and also participates in the process of heterologous desensitization between ... -
Beta-arrestin-mediated beta1-adrenergic receptor transactivation of the EGFR confers cardioprotection.
(J Clin Invest, 2007-09)Deleterious effects on the heart from chronic stimulation of beta-adrenergic receptors (betaARs), members of the 7 transmembrane receptor family, have classically been shown to result from Gs-dependent adenylyl ... -
beta-Arrestin1 modulates lymphoid enhancer factor transcriptional activity through interaction with phosphorylated dishevelled proteins.
(Proc Natl Acad Sci U S A, 2001-12-18)One aspect of the function of the beta-arrestins is to serve as scaffold or adapter molecules coupling G-protein coupled receptors (GPCRs) to signal transduction pathways distinct from traditional second messenger pathways. ... -
Binding of MetJ repressor to specific and nonspecific DNA and effect of S-adenosylmethionine on these interactions.
(Biochemistry, 2010-04-20)We have used analytical ultracentrifugation to characterize the binding of the methionine repressor protein, MetJ, to synthetic oligonucleotides containing zero to five specific recognition sites, called metboxes. For all ... -
Binding site on human immunoglobulin G for the affinity ligand HWRGWV.
(Journal of molecular recognition : JMR, 2010-05)Affinity ligand HWRGWV has demonstrated the ability to isolate human immunoglobulin G (hIgG) from mammalian cell culture media. The ligand specifically binds hIgG through its Fc portion. This work shows that deglycosylation ... -
Biomimetic nanoparticles with enhanced affinity towards activated endothelium as versatile tools for theranostic drug delivery.
(Theranostics, 2018-01-05)Activation of the vascular endothelium is characterized by increased expression of vascular adhesion molecules and chemokines. This activation occurs early in the progression of several diseases and triggers the recruitment ... -
Calmodulin dissociation regulates Myo5 recruitment and function at endocytic sites.
(EMBO J, 2010-09-01)Myosins-I are conserved proteins that bear an N-terminal motor head followed by a Tail Homology 1 (TH1) lipid-binding domain. Some myosins-I have an additional C-terminal extension (C(ext)) that promotes Arp2/3 complex-dependent ... -
Co-regulation of nuclear respiratory factor-1 by NFkappaB and CREB links LPS-induced inflammation to mitochondrial biogenesis.
(J Cell Sci, 2010-08-01)The nuclear respiratory factor-1 (NRF1) gene is activated by lipopolysaccharide (LPS), which might reflect TLR4-mediated mitigation of cellular inflammatory damage via initiation of mitochondrial biogenesis. To test this ... -
