  1. 1. G protein-coupled receptor regulation: The role of protein interactions and receptor trafficking

    Författare :Caroline Sandén; Drug Target Discovery; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; receptor trafficking; B1 receptor; receptor oligomerization; estrogen; GPER1; G protein-coupled estrogen receptor 1; EP24.15; BK; bradykinin; B1R; B2R; B2 receptor; GPCR; receptor maturation;

    Sammanfattning : The superfamily of G protein-coupled receptors (GPCR) is the largest gene family in the human genome. GPCR-mediated signaling operates in every human cell, and about 50% of existing clinically useful drugs act through GPCR. LÄS MER

  3. 2. Molecular simulations of G protein-coupled receptors : A journey into structure-based ligand design and receptor function

    Författare :Pierre Matricon; Jens Carlsson; Bjørn Olav Brandsdal; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; G Protein-Coupled Receptor; Molecular Dynamics Simulations; Free Energy Perturbation; Ligand Binding; Fragment-Based Lead Discovery; Molecular Docking Screens; Homology Modeling; GPCR Activation Mechanism; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Sammanfattning : The superfamily of G protein-coupled receptors (GPCRs) contains a large number of important drug targets. These cell surface receptors recognize extracellular signaling molecules, which stimulates intracellular pathways that play major roles in human physiology. LÄS MER

  4. 3. Free energy calculations of G protein-coupled receptor modulation : New methods and applications

    Författare :Willem Jespers; Hugo Gutiérrez-de-Terán; Johan Åqvist; Jonathan Essex; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; G protein-coupled receptor; adenosine receptor; molecular dynamics; free energy perturbation; homology modeling; computer simulations; conformational selectivity; binding free energy.; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Sammanfattning : G protein-coupled receptors (GPCRs) are membrane proteins that transduce the signals of extracellular ligands, such as hormones, neurotransmitters and metabolites, through an intracellular response via G proteins. They are abundant in human physiology and approximately 34% of the marketed drugs target a GPCR. LÄS MER

  5. 4. Classification, Evolution, Pharmacology and Structure of G protein-coupled Receptors

    Författare :Malin C Lagerström; Helgi B. Schiöth; Robert Fredriksson; Anthony J. Harmar; Uppsala universitet; []

    Sammanfattning : 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. LÄS MER

  7. 5. Evolution of the G protein-coupled receptor signaling system : Genomic and phylogenetic analyses

    Författare :Arunkumar Krishnan; Helgi Schiöth; Torgeir Hvidsten; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; GPCRs; G proteins; Sensory system; Signal transduction; Olfaction; Chemosensation; Hemichordates; Sponges; Porifera; Bilaterians; Holozoans; Fungi; Opisthokonts; Bioinformatics; Bioinformatik;

    Sammanfattning : Signal transduction pathways mediated by G protein-coupled receptors (GPCRs) and their intracellular coupling partners, the heterotrimeric G proteins, are crucial for several physiological functions in eukaryotes, including humans. This thesis describes a broad genomic survey and extensive comparative phylogenetic analysis of GPCR and G protein families from a wide selection of eukaryotes. LÄS MER
