<prompt> True about G-protein receptor complexIt interacts transmembrane domainGTP to GDPAdenyl cyclase activation leads to increased cAMPGPCR has no phosphorylation propey  <response>: G protein-coupled receptors GPCRs which are also known as seven-transmembrane domain receptors, 7TM receptors, heptahelical receptors, serpentine receptor, and G protein-linked receptors GPLR, constitute a large protein family of receptors, that sense molecules outside the cell and activate inside signal transduction pathways and, ultimately, cellular responses.Coupling with G proteins, they are called seven-transmembrane receptors because they pass through the cell membrane seven times.
