Both Ligand- and Cell-Specific Parameters Control Ligand Agonism in a Kinetic Model of G Protein–Coupled Receptor Signaling [PDF]

open access: yes, 2007
G protein–coupled receptors (GPCRs) exist in multiple dynamic states (e.g., ligand-bound, inactive, G protein–coupled) that influence G protein activation and ultimately response generation. In quantitative models of GPCR signaling that incorporate these

G-protein coupled receptor structure

open access: yesBiochimica et Biophysica Acta (BBA) - Biomembranes, 2007
Because of their central role in regulation of cellular function, structure/function relationships for G-protein coupled receptors (GPCR) are of vital importance, yet only recently have sufficient data been obtained to begin mapping those relationships. GPCRs regulate a wide range of cellular processes, including the senses of taste, smell, and vision,

Regulating G protein-coupled receptors by topological inversion

open access: yeseLife, 2019
G protein-coupled receptors (GPCRs) are a family of proteins containing seven transmembrane helices, with the N- and C-terminus of the protein located at the extracellular space and cytosol, respectively.

Calcium-independent inhibitory G-protein signaling induces persistent presynaptic muting of hippocampal synapses [PDF]

open access: yes, 2011

Thrombin Protease-activated Receptor-1 Signals through Gq- and G13-initiated MAPK Cascades Regulating c-Jun Expression to Induce Cell Transformation [PDF]

open access: yes, 2003
Although the ability of G protein-coupled receptors to stimulate normal and aberrant cell growth has been intensely investigated, the precise nature of the molecular mechanisms underlying their transforming potential are still not fully understood.

G-protein-coupled receptor kinases

open access: yesKidney International, 1996
beta-Adrenergic receptors are prototypes of the many G-protein-coupled receptors. Activation and inactivation of these receptors are regulated by multiple mechanisms which can affect either their function or their expression. The most obvious changes of such receptor systems are induced by activation of the receptors themselves by their respective ...

Presynaptic G Protein-Coupled Receptors: Gatekeepers of Addiction?

open access: yesFrontiers in Cellular Neuroscience, 2016
Drug abuse and addiction cause widespread social and public health problems, and the neurobiology underlying drug actions and drug use and abuse is an area of intensive research.
