G Protein-coupled Receptor Signaling
Description
G protein-coupled receptors are a major class of cell-surface receptors. They help cells detect signals outside the cell and pass that information inward. These receptors are important in many kinds of cell communication.
When a signal binds to a G protein-coupled receptor, the receptor changes s...

Transcript
I recettori accoppiati a proteine G o GPCR sono recettori di superficie cellulare che si associano alle proteine G eterotrimeriche e mediano la risposta cellulare a segnali come luce, ormoni, citochine e neurotrasmettitori.
Tutti i GPCR contengono sette alfa-eliche transmembrana separate da anse citosoliche alternate che legano una protei...
