Web5 jun. 2024 · GPCR-mediated signalling can occur via G-protein-dependent and G-protein-independent pathways [ 3 ]. The classical signalling through GPCRs is mediated by heterotrimeric G-proteins, comprised of α, β, and γ subunits. In the inactive state, the Gα subunit of the heterotrimer is bound to GDP.
