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 ... -
3-[211At]astato-4-fluorobenzylguanidine: a potential therapeutic agent with prolonged retention by neuroblastoma cells.
(Br J Cancer, 1997)An analogue of meta-iodobenzylguanidine (MIBG) in which an aromatic hydrogen was replaced with fluorine has been found to possess many properties similar to those of the parent compound. Moreover, 4-fluoro-3-iodobenzylguanidine ... -
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 variant at miRNA-122 binding site in IL-1a 3' UTR predicts risk of recurrence in patients with oropharyngeal cancer.
(Oncotarget, 2016-06)IL-1a, an important regulator of immune and inflammation responses, has been implicated in cancer development and prognosis. An insertion (Ins)/deletion (Del) polymorphism (IL-1a rs3783553) in the 3' UTR of IL-1a may disrupt ... -
A kinesin motor in a force-producing conformation.
(BMC Struct Biol, 2010-07-05)BACKGROUND: Kinesin motors hydrolyze ATP to produce force and move along microtubules, converting chemical energy into work by a mechanism that is only poorly understood. Key transitions and intermediate states in the process ... -
A mutation in TNNC1-encoded cardiac troponin C, TNNC1-A31S, predisposes to hypertrophic cardiomyopathy and ventricular fibrillation.
(The Journal of biological chemistry, 2012-09)Defined as clinically unexplained hypertrophy of the left ventricle, hypertrophic cardiomyopathy (HCM) is traditionally understood as a disease of the cardiac sarcomere. Mutations in TNNC1-encoded cardiac troponin C (cTnC) ... -
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, ... -
A TGF-β1 genetic variant at the miRNA187 binding site significantly modifies risk of HPV16-associated oropharyngeal cancer.
(International journal of cancer, 2018-09)TGF-β1rs1982073 polymorphism at the miRNA-187 binding site may alter TGF-β1 expression and function, and thereby this polymorphism (genotype CT/CC) increases cancer susceptibility. HPV16 L1 seropositivity is associated with ... -
An Evolutionary Insertion in the Mxra8 Receptor-Binding Site Confers Resistance to Alphavirus Infection and Pathogenesis.
(Cell host & microbe, 2020-03)Alphaviruses are emerging, mosquito-transmitted RNA viruses with poorly understood cellular tropism and species selectivity. Mxra8 is a receptor for multiple alphaviruses including chikungunya virus (CHIKV). We discovered ... -
beta2-Adrenergic receptor regulation by GIT1, a G protein-coupled receptor kinase-associated ADP ribosylation factor GTPase-activating protein.
(Proc Natl Acad Sci U S A, 1998-11-24)G protein-coupled receptor activation leads to the membrane recruitment and activation of G protein-coupled receptor kinases, which phosphorylate receptors and lead to their inactivation. We have identified a novel ... -
Conformational kinetics reveals affinities of protein conformational states.
(Proc Natl Acad Sci U S A, 2015-07-28)Most biological reactions rely on interplay between binding and changes in both macromolecular structure and dynamics. Practical understanding of this interplay requires detection of critical intermediates and determination ... -
Control of cyclin B1 localization through regulated binding of the nuclear export factor CRM1.
(Genes Dev, 1998-07-15)Activation of the Cyclin B/Cdc2 kinase complex triggers entry into mitosis in all eukaryotic cells. Cyclin B1 localization changes dramatically during the cell cycle, precipitously transiting from the cytoplasm to the nucleus ... -
DNA mismatches reveal conformational penalties in protein-DNA recognition.
(Nature, 2020-11)Transcription factors recognize specific genomic sequences to regulate complex gene-expression programs. Although it is well-established that transcription factors bind to specific DNA sequences using a combination of base ... -
Evolutionary genomics and adaptive evolution of the Hedgehog gene family (Shh, Ihh and Dhh) in vertebrates.
(PLoS One, 2014)The Hedgehog (Hh) gene family codes for a class of secreted proteins composed of two active domains that act as signalling molecules during embryo development, namely for the development of the nervous and skeletal systems ... -
Explicit DNase sequence bias modeling enables high-resolution transcription factor footprint detection.
(Nucleic Acids Res, 2014-10-29)DNaseI footprinting is an established assay for identifying transcription factor (TF)-DNA interactions with single base pair resolution. High-throughput DNase-seq assays have recently been used to detect in vivo DNase footprints ... -
Finding regulatory DNA motifs using alignment-free evolutionary conservation information.
(Nucleic Acids Res, 2010-04)As an increasing number of eukaryotic genomes are being sequenced, comparative studies aimed at detecting regulatory elements in intergenic sequences are becoming more prevalent. Most comparative methods for transcription ... -
Functionally active targeting domain of the beta-adrenergic receptor kinase: an inhibitor of G beta gamma-mediated stimulation of type II adenylyl cyclase.
(Proc Natl Acad Sci U S A, 1994-04-26)The beta-adrenergic receptor kinase (beta ARK) phosphorylates its membrane-associated receptor substrates, such as the beta-adrenergic receptor, triggering events leading to receptor desensitization. beta ARK activity is ... -
How the kinetochore couples microtubule force and centromere stretch to move chromosomes.
(Nature cell biology, 2016-04)The Ndc80 complex (Ndc80, Nuf2, Spc24 and Spc25) is a highly conserved kinetochore protein essential for end-on anchorage to spindle microtubule plus ends and for force generation coupled to plus-end polymerization ... -
