  2. 21. Characterization and Evolution of Transmembrane Proteins with Focus on G-protein coupled receptors in Pre-vertebrate Species

    Author : Karl J. V. Nordström; Helgi B. Schiöth; Robert Fredriksson; Teresa Attwood; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; G protein-coupled receptors; GPCR; Membrane protein; Rhodopsin; Adhesion; Secretin; Evolution; Bioinformatics; Phylogeny; Pharmacological research; Farmakologisk forskning; Bioinformatics; Bioinformatik; Bioinformatik; Bioinformatics; Biology with specialization in Molecular Evolution; Biologi med inriktning mot molekylär evolution;

    Abstract : G protein-coupled receptors (GPCRs) are one of the largest protein families in mammals. GPCRs are instrumental for hormonal and neurotransmitter signalling and are important in all major physiological systems of the body. READ MORE

  4. 22. Structure, evolution and expression of glandular kallikrein genes

    Author : Yvonne Ceder; Malmö Klinisk kemi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ileum.; Clinical chemistry; Klinisk kemi; Tissue distribution; Androgen responsive element; Ortholog; Evolution; Prostate cancer; Glandular kallikreins; Prostate-specific antigen;

    Abstract : Prostate-specific antigen (PSA) is a worldwide used tool for the diagnosis and monitoring of prostate cancer. It is a serine protease and belongs to the family of glandular kallikreins. Humans have three classical glandular kallikreins, but it has been reported that rodents have many more. READ MORE

  5. 23. Molecular Evolution of Neuropeptide Y Receptors in Vertebrates

    Author : Erik Salaneck; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Neuropeptide Y; Receptor; Evolution; Neurovetenskap; Neurology; Neurologi; Neurology; neurologi;

    Abstract : The three evolutionarily related peptides neuropeptide Y (NPY), peptide YY (PYY) and pancreatic polypeptide (PP) are ligands to at least five G-protein coupled receptors in mammals, which are denoted by numbers. NPY has many physiological effects including stimulation of appetite and regulation of circadian rhythm and blood pressure. READ MORE

  6. 24. Evolution of genetic mechanisms regulating reproductive development in plants : Characterisation of MADS-box genes active during cone development in Norway spruce

    Author : Jens Sundström; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Picea abies; evolution; flower development; transcription factor; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; fysiologisk botanik; Physiological Botany;

    Abstract : The reproductive organs of conifers and angiosperms differ in morphology in several fundamental respects. The conifer Norway spruce (Picea abies) form pollen and seed cones from separate meristems whereas angiosperms bear bipartite flowers with sepals and petals surrounding two inner whorls of stamens and carpels.

  7. 25. Classification, Evolution, Pharmacology and Structure of G protein-coupled Receptors

    Author : Malin C Lagerström; Helgi B. Schiöth; Robert Fredriksson; Anthony J. Harmar; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacology; Classification; Structure; Pharmacology; Evolution; G protein-coupled receptor; Farmakologi; Pharmacological research; Farmakologisk forskning;

    Abstract : G protein-coupled receptors (GPCR) are integral membrane proteins with seven α-helices that translate a remarkable diversity of signals into cellular responses. The superfamily of GPCRs is among the largest and most diverse protein families in vertebrates. READ MORE
