376 Jorgensen, ErikMolecular basis of synaptic vesicle cargo recognition by the endocytic sorting adaptor stonin 2Synaptic transmission depends on clathrin-mediated recycling of synaptic vesicles (SVs). How select SV proteins are targeted for internalization has remained elusive. Stonins are evolutionarily conserved adaptors dedicated to endocytic sorting of the SV protein synaptotagmin. Our data identify the m...2007
377 Beckerle, Mary C.Molecular characterization of human zyxinZyxin is a component of adhesion plaques that has been suggested to perform regulatory functions at these specialized regions of the plasma membrane. Here we describe the isolation and characterization of cDNAs encoding human and mouse zyxin.Zyxin; Proline; LIM domains1996
378 Beckerle, Mary C.Molecular dissection of a LIM domainLIM domains are novel sequence elements that are found in more than 60 gene products, many of which function as key regulators of developmental pathways. The LIM domain, characterized by the cysteine-rich consensus CX2CX16_23HX2CX2CX2CX16_21CX2-3(C/H/ D), is a specific metal-binding structure tha...LIM domains; Metal-binding; Zyxin; Cysteine-rich proteins1997
379 Beckerle, Mary C.Molecular dissection of zyxin function reveals its involvement in cell motilitySpatially controlled actin filament assembly is critical for numerous processes, including the vectorial cell migration required for wound healing, cell-mediated immunity, and embryogenesis. One protein implicated in the regulation of actin assembly is zyxin, a protein concentrated at sites where t...Zyxin; Actinin; Ena/VASP1999

384 Blair, David F.MotA protein of E. coli is a proton-conducting component of the flagellar motorA number of mutants of motA, a gene necessary for flagellar rotation in E. coli, were isolated and characterized. Many mutations were dominant, owing to competition between functional and nonfunctional MotA for a limited number of sites on the flagellar motor. A new class of mutant was discovered...MotA protein; MotA gene; Flagellar motor; Proton-conducting1990
385 Goller, FranzMotor control of crystallized song is modified by sensory feedbackSong production requires precisely coordinated activity in the respiratory and syringcal (vocal organ) muscles. Crystallized adult song is characterized by acoustic and motor stereotypy which does not require auditory feedback, suggesting it is represented by fixed central motor programs. To determ...Air injection; Auditory feedback; Pressure1997
386 Goller, FranzMotor control of sound frequency in birdsong involves the interaction between air sac pressure and labial tensionFrequency modulation is a salient acoustic feature of birdsong. Its control is usually attributed to the activity of syringeal muscles, which affect the tension of the labia responsible for sound production. We use experimental and theoretical tools to test the hypothesis that for birds producing to...2014-01-01
387 Lawton, Kristy J.Motor neurons tune premotor activity in a vertebrate central pattern generatorCentral patterns generators (CPGs) are neural circuits that drive rhythmic motor output without sensory feedback. Vertebrate CPGs are generally believed to operate in a top-down manner in which premotor interneurons activate motor neurons that in turn drive muscles. In contrast, the frog (Xenopus la...CPG; feed back; synchrony; vocal; vocalization; Xenopus2017
388 Eichwald, Ernst; Capecchi, Mario R.; Thomas, Kirk R.Mouse model for the delta F508 allele of cystic fibrosisThe most common cause of cystic fibrosis is a mutation that deletes phenylalanine 508 in cystic fibrosis transmembrane conductance regulator (CFTR). The delta F508 protein is misprocessed and degraded rather than traveling to the apical membrane. We used a novel strategy to introduce the delta F508 ...Digestive System; Disease Models, Animal; Electrolytes; Mice, Inbred C57BL1995-10
389 Olivera, Baldomero M.Multiple bromotryptophan and y-carboxyglutamate residues in a Conus peptideA novel peptide was purified from Conus textile venom which caused hyperactivity in mice. The 31-amino acid peptide has six residues with unusual post-translational modifications: four y-carboxyglutamates and two brominated tryptophan residues. This peptide, which we have designated the dibromorunn...1999-01-01
390 Jorgensen, ErikMultiple transcripts from the Antennapedia gene of Drosophila melanogasterThe structures of four major transcripts from the homeotic gene Antennapedia of Drosophila melanogaster were determined. These transcripts constitute two RNA classes, each class initiating from a unique promoter but sharing 3' exons. Within the shared sequences is a major open reading frame encoding...Mutations; Sequences ; RNA1986
391 Beckerle, Mary C.Muscle LIM proteins are associated with muscle sarcomeres and require dMEF2 for their expression during Drosophila myogenesisA genetic hierarchy of interactions, involving myogenic regulatory factors of the MyoD and myocyte enhancer-binding 2 (MEF2) families, serves to elaborate and maintain the differentiated muscle phenotype through transcriptional regulation of muscle-specific target genes.LIM domains; Cysteine-rich proteins1999
392 Goller, FranzMuscular control and biomechanics of the songbird syrinxIn songbirds the vocal organ, the syrinx, is controlled by six bilateral muscles, the functional roles of which have been studied indirectly, but not directly. We filmed the syrinx with an endoscope while electrically stimulating individual intrinsic muscles on one side.Syringeal; Medial labium; Vocal organ1997

We have used genetic, biochemical, and cell biological appr...Drosophila Ena; VASP1998
397 Jorgensen, ErikMutations in synaptojanin disrupt synaptic vesicle recyclingSynaptojanin is a polyphosphoinositide phosphatase that is found at synapses and binds to proteins implicated in endocytosis. For these reasons, it has been proposed that synaptojanin is involved in the recycling of synaptic vesicles. Here, we demonstrate that the unc-26 gene encodes the Caenorhab...2000
398 Jorgensen, ErikMutations in β-spectrin disrupt axon outgrowth and sarcomere structureB-Spectrin is a major component of the membrane skeleton, a structure found at the plasma membrane of most animal cells. B-Spectrin and the membrane skeleton have been proposed to stabilize cell membranes, generate cell polarity, or localize specific membrane proteins. We demonstrate that the Caen...2000
399 Capecchi, Mario R.N-formylmethionyl-sRNA as the initiator of protein synthesis.A bizarre fast about Nterminal groups of bacterial proteins. Instead of a random mixture, that the great majority of N-terminal groups were either methionine or alanine. This finding suggested that methionine and alanine constituted start signals for the initiation of polypeptide chains. Alternative...Electrophoresis; Formates; In Vitro; Methionine1966-01-01
400 Jorgensen, ErikNano-fEM: Protein localization using photo-activated localization microscopy and electron microscopyMapping the distribution of proteins is essential for understanding the function of proteins in a cell. Fluorescence microscopy is extensively used for protein localization, but subcellular context is often absent in fluorescence images. Immuno-electron microscopy, on the other hand, can localize pr...2012-01-01
