The PKA regulatory subunit from yeast forms a homotetramer: Low-resolution structure of the N-terminal oligomerization domain
(Elsevier, 2015-12)
The cAMP dependent protein kinase (PKA) is a key enzyme involved in many cellular processes in eukaryotes. In mammals, the regulatory (R) subunit localises the catalytic (C) subunit to specific subcellular sites through ...
Self-Assembled Monolayers of NH2‑Terminated Thiolates: Order, pKa, and Specific Adsorption
(American Chemical Society, 2013-01)
Self-assembled monolayers (SAMs) of amino-terminated alkanethiols on Au were characterized by a combination of electrochemical (LSV, CV, and EIS) and spectroscopic (XPS and SER) techniques. Clear correlations were obtained ...
Uncovering the relationship between the structure and acid-base properties for hyperbranched polyester-polyols self-assembled on carbon surfaces
(Elsevier Science SA, 2021-01)
The self-assembly of three different generations of hyperbranched polyester-polyol polymers, based on 2,2-bis(methylol)propionic acid units (H20, H30, and H40 Boltorn®), on carbon electrodes was studied. The physico-chemical ...
Investigação sobre calicreína plasmática humana em linhagens de tumor de mama: envolvimento com a ativação do plasminogênio e sindecans
(Universidade Federal de São Paulo, 2022-11-28)
Objetivo: Investigar a presença das proteínas do SAP, a PK e os PGHS em linhagens de tumor de mama receptoras de hormônio positivas (MCF-7). Métodos: A expressão de mRNA foi obtida por PCR em tempo real (qPCR) usando primers ...
Efeito do tipo de éter amina na hidrofobicidade do quartzo no processo de flotação catiônica reversa de minério de ferro
(Universidade Federal de Minas GeraisUFMG, 2017-06-29)
The cationic reverse flotation route is one of the main processes to remove quartz from iron ore. The ether amines are the most common surfactant used to modify quartzs surface hydrophobicity from hydrophilic to hydrophobic. ...
Cholesterol depletion induces PKA-mediated basolateral-to-apical transcytosis of the scavenger receptor class B type I in MDCK cells
(NATL ACAD SCIENCES, 2004)
Cholesterol-based membrane microdomains, or lipid rafts, are believed to play important, yet poorly defined, roles in protein trafficking and signal transduction. In polarized epithelial cells, the current view is that ...
Photophysicochemical characterization of mycosporine-like amino acids in micellar solutions
(Royal Society of Chemistry, 2017-07)
The properties and photochemical and photophysical behavior of the mycosporine-like amino acids (MAAs) shinorine and porphyra-334 were experimentally evaluated in solutions of direct ionic micelles as simple biomimicking ...
Adsorção de 5 fluorouracil e 5 clorouracil sobre HOPG : um estudo da importância do estado de protonação via microscopia de varredura por tunelamento
(Universidade Federal de SergipePós-Graduação em Ciência e Engenharia de MateriaisBRUFS, 2017)
Graphite Screen-printed Electrodes Applied For The Accurate And Reagentless Sensing Of Ph
