G-Protein-Coupled Receptor Dimers

G-protein-coupled receptors (GPCRs) are believed to be the largest family of membrane proteins involved in signal transduction and cellular responses.

Receptorii cuplati la proteina G (GPCR) sunt considerati a fi cea mai mare familie de proteine de membrana implicate in transductia semnalului si in raspunsurile celulare. Se dimerizeaza (formeaza o pereche de macromolecule) cu o mare varietate de alti receptori.
