    Författare :Aneta I. Ringholm; Helgi B. Schiöth; Dan Larhammar; Björn Olde; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacology; evolution; melanocortin; MSH; pharmacology; genome duplication; tetraploidization; zebrafish; spiny dogfish; chicken; GPCR; polymorphism; pigmentation; Farmakologi; Pharmacological research; Farmakologisk forskning;

    Sammanfattning : The melanocortin (MC) receptors are G-protein coupled receptors thatparticipate in several important physiological functions such as the regulation of the energy balance. This thesis focuses on the evolutionary aspect of the MC receptors and their pharmacology.One MC4 receptor and two MC5 receptor subtypes were found in a teleost fish, zebrafish. LÄS MER

    Sammanfattning : Seven-transmembrane, G-protein coupled receptors play a central role in physiology since they facilitate cell communication in multicellular organisms by recognition of a broad range of ligands. They also represent important drug targets. LÄS MER

  5. 14. G Protein-Coupled Receptors; Discovery of New Human Members and Analyses of the Entire Repertoires in Human, Mouse and Rat

    Författare :David E. Gloriam; Helgi Schiöth; Robert Fredriksson; Darren Flower; Uppsala universitet; []
    Nyckelord :Bioinformatics; G protein-coupled receptor; GPCR; Bioinformatics; Evolution; Orphan; Rhodopsin; Adhesion; Phylogeny; Bioinformatik;

    Sammanfattning : G protein-coupled receptors (GPCRs) are signal mediators that have a prominent role in the regulation of physiological processes and they make up the targets for 30-45% of all drugs. Papers I and II describe the discovery of new human GPCRs belonging to the Rhodopsin family, a family which contains many common drug targets. LÄS MER
