A.) List two general ways that phosphorylation by a kinase can promote intracellular signaling? B.) Explain why, in the absence of inhibitor, epinephrine stimulation results in the presence of beta arrestin band, which is absent in inhibitor treated samples.

Describe the common features shared by GPCRs and RTKs in their signaling mechanisms, focusing on how they are able to amplify signals. Specifically, how is the signal from one binding event (i.e., the binding of one ligand molecule to an individual receptor) propagated and strengthened? Describe one difference in how GPCRs and RTKs transform extracellular signals into intracellular responses.

6. Specific structural features tag proteins for transport to various intracellular and extracellular destinations. Several examples were described in chapter 12, including (1) the short peptide Lys-Asp-Glu-Leu, (2) characteristic hydrophobic membrane-spanning domains, and (3) mannose-6-phosphate residues attached to oligosaccharide side chains. For each structural feature, answer the following questions with detail: a. Where in the cell is the tag incorporated into the protein? b. How does the tag ensure that the protein reaches its destination? c. Where would the protein...

What are some key signaling pathways/intracellular molecules involved in cell signaling (how does this relate to stress response, cell remodeling, cell cycle, migration, membrane composition)?

Explain in as much detail as possible, how intracellular signaling leads to a signal amplification.

Explain why "transduction" does not occur for signaling pathways that employ an intracellular receptor.

For a biological response activated by a cell signaling receptor due to stimulation by a related set of ligands (signaling molecules): a) For any one particular type of ligand: Provide your best thinking about the mechanisms underlying the fact that the response is stronger when the concentration of ligand is higher. b) A and B, a pair of structurally similar but different ligands, are presented separately but at the same concentration to separate samples of cells from a highly uniform...
