Concept explainers

Cell Signaling

It allows cells to perform various cellular activities, coordinate, and interact with other cells. All cells of an organism receive signals from their environments and respond accordingly. Even the unicellular eukaryotes receive signals secreted by other cells and respond. In the case of yeast, mating takes place by signaling between the yeast cells. Communication by cell signaling in a multicellular organism has become a vast and important part of various fields of biology.

Can I get help on how to do this question? Two mutations have occurred to proteins within the glucagon signaling pathway: A) The glucagon receptor has a mutation. This mutation causes this GPCR to always have a conformation that will induce nucleotide exchange for any associated heterotrimeric G proteins, even without glucagon binding to the receptor. B) The alpha subunit of the heterotrimeric G protein has a mutation. This mutation causes the Gαarginine finger to always be in a position to properly order the catalytic residues within the Gαsubunit to promote catalysis. Question: What will the effect of the glucagon receptor mutation be on the GPCRs function and what is the mechanistic reason for this effect?
