Each GPCR can bind several transducers, G proteins, GPCR kinases (GRKs) and arrestins leading to distinct intracellular signaling networks and functional outcomes. 423 Human proteins.
WebMar 5, 2024 · The binding of a signal molecule by the extracellular part of the G-protein linked receptor causes the cytosolic tail of the receptor to interact with, and alter the conformation of, a G-protein. This has two consequences: First, the alpha subunit of the G- protein loses its GDP and binds a GTP instead. G-protein-coupled receptor kinase (GRK) adalah modulator kunci pensinyalan GPCR.
