describing a ligand’s interaction with G-protein coupled receptor pathway. The individual steps of signal transduction must be clear from receptor binding to cellular response.
Homework Answers
GPCR interact with G proteins in the plasma membrane( In
inactive state GPCR is bound to a heterotrimeric G protein complex,
the Gα subunit is bound to GDP and is firmly attached to the Gβ and
Gγ subunits) ---binding of an external signaling molecule in the
form of a ligand--- conformational change in the receptor(
transmission of bound Gα subunit to active status,exchange of GDP
to GTP, dissociation of Gα subunit from the Gβγ dimer and from the
receptor.)---dissociated Gα and Gβγ subunits interact with other
intracellular proteins---
signal transduction cascade
