G-protein coupled receptors (GPCR) interact with
drugs through 7 regions of proteins that span and
innervate the cell membrane and trap the molecule
into the receptor site like an interwoven basket (Insel
& Sriram, 2018). Drugs can then enter this space and
interact with the GRCP. A specific interaction and
G-Protien coupled binding with a site on one or more of the regions of
receptors and how they proteins within the GPCR, and drugs bound with the
interact with drugs GRCP can stimulate the release of G proteins that can
interact with various effector proteins to create
physiological responses within the body (Insel &
Sriram, 2018). This process occurs through secondary
messengers (such as cAMP) which creates the
extracellular interactions produced by the drug
binding to the GRCP.
