- Histamine binds to the H1 G-protein-linked receptor to initiate the itchiness and airway constriction associated with an allergic response. If a mutation in the associated G-protein’s alpha subunit prevented the hydrolysis of GTP how would the allergic response change? More severe allergic response compared to normal G-protein signaling. Less severe allergic response compared to normal G-protein signaling. No allergic response. No change compared to normal G-protein signaling.What property enables the residues of the amino acids serine, threonine, and tyrosine to be phosphorylated? They are polar. They are non-polar. They contain a hydroxyl group. They occur more frequently in the amino acid sequence of signaling proteins.Regions of 2 receptors that interact on dimerization are shown below. Identify the types of interactions between amino acids based on their interacting side chains (figures of amino acids also provided).

PI3K 740, 751+ 1021 GAP 771 +] +] PTP 1009 PLC PLCy PLCT 1021 When activated by ligand binding, the PDGF (platelet-derived growth factor) receptor becomes phosphorylated on 5 tyrosine residues (left figure). These phosphorylated tyrosines serve as binding sites for proteins that contain SH2 domains (SH2 domains bind phosphorylated Y). These proteins include phospholipase C-gamma (PLC-gamma), a phosphotyrosine phosphatase (PTP), a Ras GTPase-Activating Protein (GAP), and a phosphotidylinositol 3-Kinase (PI3K). PDGF stimulates several changes in the target cell, one of which is DNA synthesis. To determine which effectors of the PDGF receptor is/are responsible for stimulating DNA synthesis, you construct several mutant forms of the receptor that retain individual or combinations of the phosphorylation sites. You express these in cells and monitor DNA synthesi The results are shown in the right…
