Rad23 interaction with the proteasome is regulated by phosphorylation of its ubiquitin-like (UbL) domain.
J. Mol. Biol. 426(24) , 4049-60, (2014) Rad23 was identified as a DNA repair protein, although a role in protein degradation has been described. The protein degradation function of Rad23 contributes to cell cycle progression, stress response, endoplasmic reticulum proteolysis, and DNA repair. Rad23... |

Mechanism of chemical activation of sodium chloride in the presence of amino acids.
Food Chem. 166 , 301-8, (2014) Sodium chloride has been shown to promote chlorination of glycerol during thermal processing. However, the detailed mechanism of this reaction is not well understood. Preliminary experiments have indicated that the reaction mixture should contain an amino aci... |

EAAT2 (GLT-1; slc1a2) glutamate transporters reconstituted in liposomes argues against heteroexchange being substantially faster than net uptake.
J. Neurosci. 34(40) , 13472-85, (2014) The EAAT2 glutamate transporter, accounts for >90% of hippocampal glutamate uptake. Although EAAT2 is predominantly expressed in astrocytes, ∼10% of EAAT2 molecules are found in axon terminals. Despite the lower level of EAAT2 expression in glutamatergic term... |

Silica-based nanofibers for electrospun ultra-thin layer chromatography.
J. Chromatogr. A. 1364 , 261-70, (2014) Nanofibrous silica-based stationary phases for electrospun ultra-thin layer chromatography (E-UTLC) are described. Nanofibers were produced by electrospinning a solution of silica nanoparticles dispersed in polyvinylpyrrolidone solutions to create composite s... |

8DSS-promoted remineralization of initial enamel caries in vitro.
J. Dent. Res. 93(5) , 520-4, (2014) Peptides containing 8 repeats of aspartate-serine-serine (8DSS) have been shown to promote the nucleation of calcium phosphate from solution into human enamel. Here we tested the ability of 8DSS to promote the remineralization of demineralized enamel in an in... |

Fluoride exposure regulates the elongation phase of protein synthesis in cultured Bergmann glia cells.
Toxicol. Lett. 229(1) , 126-33, (2014) Fluoride is an environmental pollutant present in dental products, food, pesticides and water. The latter, is the greatest source of exposure to this contaminant. Structural and functional damages to the central nervous system are present in exposed populatio... |

Low resolution X-ray structure of γ-glutamyltranspeptidase from Bacillus licheniformis: opened active site cleft and a cluster of acid residues potentially involved in the recognition of a metal ion.
Biochim. Biophys. Acta 1844(9) , 1523-9, (2014) γ-Glutamyltranspeptidases (γ-GTs) cleave the γ-glutamyl amide bond of glutathione and transfer the released γ-glutamyl group to water (hydrolysis) or acceptor amino acids (transpeptidation). These ubiquitous enzymes play a key role in the biosynthesis and deg... |

Chemical genetics reveals a complex functional ground state of neural stem cells.
Nat. Chem. Biol. 3(5) , 268-273, (2007) The identification of self-renewing and multipotent neural stem cells (NSCs) in the mammalian brain holds promise for the treatment of neurological diseases and has yielded new insight into brain cancer. However, the complete repertoire of signaling pathways ... |
