The nuclear-to-cytoplasmic ratio drives cellularization in the close animal relative Sphaeroforma arctica

The ratio of nuclear content to cytoplasmic volume (N/C ratio) is a key regulator driving the maternal-to -zy-gotic transition in most animal embryos. Altering this ratio often impacts zygotic genome activation and de-regulates the timing and outcome of em ...

The N-Terminal Region of Yeast Protein Phosphatase Ppz1 Is a Determinant for Its Toxicity

Maria Lopez Malo

The Ppz enzymes are Ser/Thr protein phosphatases present only in fungi that are characterized by a highly conserved C-terminal catalytic region, related to PP1c phosphatases, and a more divergent N-terminal extension. In Saccharomyces cerevisiae, Ppz phosp ...

Receptor-independent modulation of cAMP-dependent protein kinase and protein phosphatase signaling in cardiac myocytes by oxidizing agents

Sonia Donzelli

The contraction and relaxation of the heart is controlled by stimulation of the beta 1-adrenoreceptor (AR) signaling cascade, which leads to activation of cAMP-dependent protein kinase (PKA) and subsequent cardiac protein phosphorylation. Phosphorylation i ...

Phospho-S129 Alpha-Synuclein Is Present in Human Plasma but Not in Cerebrospinal Fluid as Determined by an Ultrasensitive Immunoassay

Hilal Lashuel, Lara Petricca, Sean Michael Deguire

Accumulation and aggregation of misfolded alpha-synuclein is believed to be a cause of Parkinson's disease (PD). Phosphorylation of alpha-synuclein at S129 is known to be associated with the pathological misfolding process, but efforts to investigate the r ...

Transmembrane Prolines Mediate Signal Sensing and Decoding in Bacillus subtilis DesK Histidine Kinase

Matteo Dal Peraro, Luciano Andres Abriata

Environmental awareness is an essential attribute of all organisms. The homeoviscous adaptation system of Bacillus subtilis provides a powerful experimental model for the investigation of stimulus detection and signaling mechanisms at the molecular level. ...

Cryo-EM structure of phosphodiesterase 6 reveals insights into the allosteric regulation of type I phosphodiesterases

Henning Paul-Julius Stahlberg, Andreas Engel

Cyclic nucleotide phosphodiesterases (PDEs) work in conjunction with adenylate/guanylate cyclases to regulate the key second messengers of G protein-coupled receptor signaling. Previous attempts to determine the full-length structure of PDE family members ...

Enhanced Sensing of Interleukin 8 by Stripping Voltammetry: Carbon Nanotubes versus Fullerene

Sandro Carrara, Sarah Tonello

The ability to detect protein biomarkers at a subnanomolar level represents a pervasive challenge in order to bring a significant improvement in early diagnosis or progression of pato-physiological processes. To this aim, Screen Printed Electrochemical Sen ...

Synthesis and crystal structure of a chiral lactam and three amino alcohols as potential protein tyrosine phosphates 1B inhibitors

Rosario Scopelliti

Chiral lactam 2 and three chiral 3-amino alcohols 3-5 have been synthesized and characterized by Sspectroscopic techniques. Regioselective ring opening reaction of chiral styrene oxide by an amine nucle-ophile was confirmed by X-ray diffraction data. Ligan ...

Studying membrane-protein interplay by modeling realistic conditions

Martina Audagnotto

Realistic models of cellular environments have long captured the imagination of biologists and physical scientists. More than 20 years ago, Goodshellâs inspiring rendering of cellular environments provided the foundation for the idea of capturing the ful ...

Identification of genetic interactors of ypa2 in Schizosaccharomyces pombe

Manuela Moraru

In this study, the fission yeast Schizosaccharomyces pombe was used as a model system to study the cellular signaling that underlies cell cycle progression. Phosphorylation plays an important part in the regulation of this process. Kinases catalyze the tra ...
