- 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.Q1. Explain why GDP cannot dissociate from the alpha subunit of the Trimeric G-protein even though the receptor is activated by ligand binding and there is enough GTP for the exchange process.Need help Intaractions of FAK kinase which directly depend on the tyrosine residue 397 (Y397) are inhibbited by a chemical compound in cancercells. Intaraction of FAK kinase with what proteins are blocked by this inhibition? (please give a listt of them all, and that's it)
- BIOC 384 Receptor Tyrosine Kinase Signaling Q8.1: Explain why a glycine residue at position 12 of the G protein Ras is only active in the presence of growth factors but Ras with an aspartate residue at the same position is oncogenic (can cause cancer).. Suggest the effects of each of the following mutations on the physio- logical role of chymotrypsinogen: (a) R15S (b) Cis (c) T147SCan I get help please with 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 combined effect of both mutations be on the signaling pathway and what is the mechanistic reason for this effect?

- 3 of 16 Which statement about the IP3 DAG pathway is false? O Diacylglycerol can act as a second messenger. Inositol trisphosphate can act as a second messenger. O Protein kinase C can phosphorylate a wide variety of proteins. O Inositol trisphosphate remains bound to the membrane after phospholipase C catalyzes its formation. Inositol trisphosphate can open ion channels in the membraņes of smooth endoplasmic reticulum, releasing calcium into the cytoplasm.Tumor necrosis factor (TNF) signaling Discuss the nature of the TNF ligand and the receptor for that ligand, and explain the general steps in the pathway (use figure 8.53 and explain in your own words). Make sure to include an explanation of the proteolytic and phosphorylation cascades. What advantage is there in having a cascade part of these pathways? What purpose does it serve?1 of 16 Data from an experiment is shown in the figure below. In the experiment, murine cells were treated with a specific a ligand that activates receptor R. In some cases, the cells were exposed to one of two drugs (X or Y) as well as the ligand or were left untreated (UT). After 30 minutes of treatment, the cells were lysed with a detergent-based buffer to release the soluble membrane, cyosolic and nuclear proteins. Samples from each cell extract were run (in duplicate) by SDS-PAGE (SDS-polyacrylamide gel electrophoresis) in order to separate the proteins by molecular mass (size). The separated proteins were then transferred to a nitrocellulose membrane which was then probed with different antibodies in a western blotting procedure to detect specific phosphorylated proteins or total proteins. If present in the cell extract, these proteins appear as a dark band in the relevant western blot image within the figure. Drug X Drug Y UT Ligand Ligand Ligand Western blotting antibodies…
