The Caenorhabditis elegans and Haemonchus contortus beta-tubulin genes cannot substitute for loss of the Saccharomyces cerevisiae beta-tubulin gene.

Sophia B Gibson, Clare S Harper, Laura L Lackner, Erik C Andersen,

To better understand the mechanism of resistance caused by putative interactions between beta-tubulin and benzimidazole compounds, we sought to purify nematode-specific beta-tubulins using heterologous expression after replacement of the single <i>Saccharomyces cerevisiae</i> beta-tubulin gene. However, we found that haploid yeast cells containing nematode-specific beta-tubulin genes were not viable, suggesting that ... Read more >>

Over-expression of the constitutive AMPylase FIC-1(E274G) does not deplete cellular ATP pools in C. elegans.

Margaret Champion, Matthias C Truttmann,

Protein AMPylation has emerged as a posttranslational protein modification regulating cellular proteostasis. AMPylation is conferred by Fic AMPylases, which catalyze the covalent attachment of AMP to target proteins at the expense of ATP. Over-expression of constitutive-active Fic AMPylases is toxic. Here, we test the hypothesis that excessive Fic AMPylase activity ... Read more >>

Effects of blunt force injuries in third-instar Drosophila larvae persist through metamorphosis and reduce adult lifespan.

Jorgo Lika, Rebeccah J Katzenberger, Barry Ganetzky, David A Wassarman,

Blunt force injuries are a significant cause of disability and death worldwide. Here, we describe a <i>Drosophila melanogaster</i> model of blunt force injury that can be used to investigate cellular and molecular mechanisms that underlie the short-term and long-term effects of injuries sustained at a juvenile stage of development. Injuries ... Read more >>

Inner Nuclear Membrane Asi Ubiquitin Ligase Catalytic Subunits Asi1p and Asi3p, but not Asi2p, confer resistance to aminoglycoside hygromycin B in Saccharomyces cerevisiae.

Kelsey A Woodruff, Kyle A Richards, Melissa D Evans, Abigail R Scott, Brian M Voas, Courtney Broshar Irelan, James B Olesen, Philip J Smaldino, Eric M Rubenstein,

The heterotrimeric Asi ubiquitin ligase (encoded by <i>ASI1</i>, <i>ASI2</i>, and <i>ASI3</i>) mediates protein degradation in the inner nuclear membrane in <i>Saccharomyces cerevisiae</i>. Asi1p and Asi3p possess catalytic domains, while Asi2p functions as an adaptor for a subset of Asi substrates. We hypothesized the Asi complex is an important mediator of ... Read more >>

Novel allele elh of the UBP14 gene affects plant organ size via cell expansion in Arabidopsis thaliana.

Rakesh David, Pei Qin Ng, Lisa M Smith, Iain R Searle,

Plant organ size control is an essential process of plant growth and development. The regulation of plant organ size involves a complicated network of genetic, molecular interactions, as well as the interplay of environmental factors. Here, we report a temperature-sensitive hypocotyl elongation EMS-generated mutant, hereby referred to as <i>elongated hypocotyl ... Read more >>

Recombination and biased segregation of mitochondrial genomes during crossing and meiosis of different Schizosaccharomyces pombe strains.

Stephan Kamrad, María Rodríguez-López, Shoumit Dey, Mimoza Hoti, Henry Wallace, Markus Ralser, Jürg Bähler,

During meiosis, tethering of parental mitochondria to opposite cell poles inhibits the mixing of mitochondria with different genomes and ensures uniparental inheritance in thestandard laboratory strain of fission yeast. We here investigate mitochondrial inheritance in crosses between natural isolates using tetrad dissection and next-generation sequencing. We find that colonies grown ... Read more >>

YML018C protein localizes to the vacuolar membrane independently of Atg27p.

Candyce M Sturgeon, Nicholas Zanghi, Hannah M Smith, Emily K Davis, Meaghan R Robinson, Elizabeth Cabrera, Molly C Holbrook, Verónica A Segarra,

The function of the budding yeast YML018C protein remains to be determined. High-throughput studies have reported that the YML018C protein localizes to the vacuolar membrane and physically interacts with the autophagy-related protein Atg27p. While this evidence suggests a potential role for this uncharacterized protein in the process of autophagy, the ... Read more >>

Distinct spatiotemporal distribution of Hsp90 under high-heat and mild-heat stress conditions in fission yeast.

Teruaki Takasaki, Naofumi Tomimoto, Takumi Ikehata, Ryosuke Satoh, Reiko Sugiura,

The molecular chaperone Hsp90 is highly conserved from bacteria to mammals. In fission yeast, Hsp90 is essential in many cellular processes and its expression is known to be increased by heat stress (HS). Here, we describe the distinct spatiotemporal distribution of Hsp90 under high-heat stress (HHS: 45˚C) and mild-heat stress ... Read more >>

Atg27p co-fractionates with clathrin-coated vesicles in budding yeast.

Verónica A Segarra, Anupam Sharma, Sandra K Lemmon,

Atg27p, a single-pass transmembrane protein that functions in autophagy, localizes to a variety of cellular compartments including the pre-autophagosomal structure, late Golgi, vacuolar membrane, as well as early and late endosomes. Its cytoplasmic C-terminus contains a tyrosine sorting motif that allows for its transport to the vacuolar membrane and an ... Read more >>

Atg27p localization is clathrin- and Ent3p/5p-dependent.

Verónica A Segarra, Anupam Sharma, Sandra K Lemmon,

The autophagy-related protein Atg27p has been previously shown to localize to the autophagy-specific pre-autophagosomal structure (PAS) as well as to several organelles, including the late Golgi, the vacuolar membrane, and the endosome. Given that Atg27p localization to the vacuolar membrane in particular has been shown to be dependent on both ... Read more >>

The S1A protease family members CG10764 and CG4793 regulate cellular immunity in Drosophila.

Pooja Kr, Jonathan Lee, Nathan T Mortimer,

In nature, <i>Drosophila melanogaster</i> larvae are infected by parasitoid wasps and mount a cellular immune response to this infection. Several conserved signaling pathways have been implicated in coordinating this response, however our understanding of the integration and regulation of these pathways is incomplete. Members of the S1A serine protease family ... Read more >>

Pyrogallol induces oxidative stress defects in the fission yeast S. pombe.

Nafees Ahamad, Simmi Anjum, Shakil Ahmed,

Apart from the beneficial roles of pyrogallol in industries, it also tends to produce free radicals that trigger apoptosis in human cells. In this study, we checked the toxic effect of pyrogallol in fission yeast <i>S. pombe</i> cells. We observed that the wild type and <i>wat1/pop3</i> delete cells were unable ... Read more >>

Mutating two putative phosphorylation sites on ZHP-3 does not affect its localization or function during meiotic chromosome segregation.

Anna E Russo, Christian R Nelson, Needhi Bhalla,

Meiotic chromosome segregation depends on crossover recombination to link homologous chromosomes together and promote accurate segregation in the first meiotic division. In <i>Caenorhabditis elegans</i>, a conserved RING finger protein, ZHP-3, is essential for meiotic recombination and localizes to sites of crossover formation. Whether ZHP-3 is regulated to promote recombination remains ... Read more >>

Repetitive mild traumatic brain injury causes synergistic effects on mortality.

Ashley M Willes, Tori R Krcmarik, Alexander E Daughtry, Douglas J Brusich,

Repetitive mild TBI (rmTBI) events are common in the U.S. However, rmTBI is challenging to study and this contributes to a poor understanding of mechanistic bases for disease following these injuries. We used fruit flies (<i>D. melanogaster</i>) and a modified version of the high-impact trauma (HIT) method of TBI to ... Read more >>
