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
G-Protien coupled interaction and binding with a site on one or more
receptors and how they of the regions of proteins within the GPCR, and
interact with drugs drugs bound with the 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.
