Mutation of Polaris, an Intraflagellar Transport Protein, Shortens Neuronal Cilia
… is directly involved in a microtubule-dependent transport process called intraflagellar transport (IFT). In order to determine the importance of polaris in the development of neuronal cilia, cilium length and numerical density of cilia were quantitatively assessed in six different brain regions …

Molecular investigation if the rat jejunal active nucleoside transport protein rCNT1
Active, sodium-dependent nucleoside transport systems have been kinetically described in a number of different mammalian tissues. The recent cloning of several active, mammalian nucleoside transporters belonging to a novel gene family has provided an opportunity to examine both the …

The Role of Mammalian Lipid Transport Protein ORP1 During Coxiella Burnetii Infection
… 4B secretion system (T4SS) to secrete effector proteins into the host cell cytoplasm. While the CCV membrane is rich in sterols, cholesterol accumulation in the CCV is bacteriolytic, suggesting that C. burnetii regulation of lipid transport is critical for infection. The mammalian lipid …

Development of pseudosymmetry analysis to identify key residues in transport protein mechanisms
Transport proteins, despite making up approximately 10% of the human genome, are understudied. Multiple computational tools exist to analyse them, but no tool exists to predict which residues are likely to be involved in substrate binding or in the mechanism of the transporter. In this thesis, I …

Poly(A)+ RNA From Sheep Omasal Epithelium Induces Expression of a peptide Transport Protein(S) in Xenopus laevis Oocytes
… epithelium contains mRNA encoding for a peptide transporter (s) and to determine di- to octapeptide transport capability, poly(A)+ RNA isolated from sheep omasal epithelium was injected into Xenopus laevis oocytes. Poly(A)+ RNA was functionally expressed in Xenopus oocytes 4 to 7 d …

Isolation and Characterization of an Isoprenoid Transporter Protein in Manduca sexta
Metabolic regulation and transport is a fundamental process in all eukaryotic organisms. Metabolites synthesized throughout the cell must be used in various locations to ensure proper cell function. Isoprenoids are metabolite molecules implicated in cell growth, energy production, and act as …

Moessbauer Studies of Exchange-Coupled Two-Iron Centers in Proteins (Hemerythrin, Uteroferrin, Epr)
… measurements on three derivatives of the oxygen-transport protein hemerythrin and on the oxidized and reduced forms of uteroferrin, a purple acid phosphatase isolated from porcine uterine fluid. Both proteins contain an exchange-coupled pair of iron atoms coordinated directly to amino acid side …

Investigating nuclear transport proteins as secreted cancer biomarkers
… analysis identified members of the nuclear transport protein family as significantly upregulated in cervical cancer biopsies compared to normal cervical epithelial tissues. These results were validated at both mRNA and protein levels, and similar upregulation observed in oesophageal cancer. …

Tissue Distribution of a Peptide Transporter mRNA in Sheep, Dairy Cows, Pigs, and Chickens
… sheep omasal epithelium encoding for a peptide transport protein(s), a 446-bp cDNA fragment was cloned from sheep omasal epithelium RNA. The predicted amino acid sequence of this fragment was 85.8, 90.5, and 90.5 percent identical to rabbit, human, and rat PepT1, respectively. The fragment was …

Mechanismen des vermittelten und nicht-vermittelten Transportes einer amphiphilen Phosphonat-Sonde (NDP2) in der Erythrozytenmembran
… this translocation takes place via the membrane protein AE1(Band 3), which was originally known as a transport protein for small hydrophilic anions (e.g. chloride -ions) and the characteristics of which as a transport agent for long-chain amphiphiles is at the centre of these investigations. The …

Hexose Transport In L6 Rat Myoblasts
… the nature and the regulation of the hexose transport system in the permanent cell line, L6. This rat myoblast line can differentiate in culture to form multinucleated myotubes, but in this study, only the undifferentiated cells were used. Kinetic and inhibition studies suggested that the …
