5 Questions
What is the role of G-proteins in G-protein coupled receptor (GPCR) signaling?
G-proteins can be in active or inactive states and help in signal transduction by hydrolyzing GTP
What is the primary function of ligands in cell communication?
Ligands are signaling molecules that bind to receptor proteins to initiate the process of signal transduction
Which type of cell communication is used for long-distance signaling?
Endocrine
How were GPCRs discovered?
Using affinity chromatography to isolate receptors from solubilized membranes
What is the main characteristic of G-protein coupled receptors (GPCRs)?
They contain seven transmembrane domains and are the targets of many pharmaceutical drugs
