G-protein-independent signaling by G-protein-coupled receptors

Trends in Neurosciences, 2000
Two classes of receptors transduce neurotransmitter signals: ionotropic receptors and heptahelical metabotropic receptors. Whereas the ionotropic receptors are structurally associated with a membrane channel, a mediating mechanism is necessary to functionally link metabotropic receptors with their respective effectors.

G Protein-Coupled Receptors and G Proteins

1997
G protein-coupled receptors (GPCRs) belong to a large class of membrane-spanning receptors. GPCRs function as antennae for external signals consisting of chemical ligands or photons (in the case of opsins). Once the external signal is received, it is transduced to a cytosolic G protein. Subsequently, the G protein itself becomes activated.

G Proteins and G Protein-Coupled Receptors

2002
Cells live in a constantly changing milieu. The structure and biochemical nature of this environment is dynamic and in order for normal cellular function to proceed in a manner appropriate for the benefit of the organism, cells must be able to access this changing information.

G Protein-Coupled Receptors and G Proteins

2000
G protein-coupled receptors (GPCRs) form a large and functionally diverse superfamily of cell membrane receptors. Many signaling cascades use GPCRs to convert a large diversity of external and internal stimuli including photons, odorants, and ions as well as hormones and neurotransmitter agonists into intracellular responses.
