- Receptor tyrosine kinases such as the epidermal growth factor (EGF) receptor can basically be broken down into three domains: (1) An extracellular, ligand binding domain, (2) A transmembrane domain that must cross through the cell membrane, and (3) an intracellular domain. Match the amino acid with the domain that it would MOST LIKELY be associated with. Lysine (choose (1), (2), or (3) from above) A tyrosine residue capable of being phosphorylated on its hydroxyl group (choose (1), (2), or (3) from above) Isoleucine (choose (1), (2), or (3) from above)GTP binding proteins are molecular switches. How do GTP binding proteins work? Provide two examples of GTP binding proteins that function in intracellular protein transport. Make a drawing that illustrates the function of each of these proteins in their respective roles. Predict the direct outcome of a mutation that: Inhibits GTPase activity Inhibits interaction with the GEFSuppose that Protein J which is a hypothetical protein kinase receptor was determined to be related to the progression of cancer through its activation. It was also determined that the protein exists in the active and inactive forms. The said active form is highly similar to the Protein K's conformation. Ligands A, B, and C, which are lead inhibitor compounds, were optimized to inhibit Protein J. The affinities of the ligands are shown in the table.

- Suppose that Protein J which is a hypothetical protein kinase receptor was determined to be related to the progression of cancer through its activation. It was also determined that the protein exists in the active and inactive forms. The said active form is highly similar to the Protein K's conformation. Ligands A, B, and C, which are lead inhibitor compounds, were optimized to inhibit Protein J. The affinities of the ligands are shown in the table. Kp values Active Protein J Inactive Protein J Protein K Ligand A 10 mM 20 nM 5 mM Ligand B 20 nM 10 mM 15 nM Ligand C 20 nM 15 nM 15 nM Question: Describe the relative binding affinities of Ligand A to Protein K and to the active and inactive forms of Protein J. Determine which will Ligand A bind with the highest, medium, and lowest affinity.added ligand concentration of 10 µM is 5 × 10³ s¹. What is the value of the reverse rate constant k_1 = 1 ×10-4 Incorrect Macmillan Learning You have not correctly calculated the value of the reverse rate constant. To begin, calculate the value of k₁ by dividing the rate of receptor-ligand complex formation (the rate of the forward reaction) by the ligand concentration. k₁ = rate forward [L] Then, calculate the value of the reverse rate constant, k_₁, by multiplying the dissociation constant, Kd, and the forward rate constant, k₁. k_1 = Kak₁Compare and contrast GPCR and RTK signaling. What role does GTP play in each? What role does phosphorylation play? How do these two signaling types compare to steroid signaling with respect to gene activation?
- An SH2-containing protein contains a mutation that changes its binding pocket such that tyrosine and phosphotyrosine bind with equal affinity. As a result, MEK activity: does not change with receptor dimerization and transautophosphorylation decreases due to changes in Raf activation increases with ligand binding-induced dimerization decreases due to allosteric inhibition of SH2-domain bindingSubstrate binding causes dimerization of tyrosine kinase receptors. Why is dimerization critical to activate of the receptors?RTKs are receptors made of an extracellular ligand binding domain and an intracellular kinase domain (see image). Insulin binds to its RTK Insulin receptor, causing an increase in glucose absorption and storage in liver cells. EGF binds to its own RTK, EGFR and promotes cell growth through the Ras pathway. a) Explain why the same type of tyrosine kinase in two RTKs can lead to very different cellular responses. Give an example of potential cellular outputs for each of these two RTKs.
- Briefly describe the following properties of the Rab and Arf GTPases: a) Size, structure and cellular localization (for structure I want to know if they are lipidated and any other unique features) , b) How are they activated and inactivated (i.e. include the GEFs and GAPs), c). Give an example of downstream cellular effects.Compare and contrast GPCR and RTK signaling. What role does GTP play in each? What role does phosphorylation play? How is each signal differently amplified? How do these two signaling types compare to steroid signaling with respect to gene activation?You are studying the role of CAMP in cell signaling. You hypothesize that 2 intracellular signaling proteins, named GO and TIGERS, interact with each other when cells are treated with an extracellular source of CAMP. The two proteins were tagged with CFP or YFP (CFP = cyan fluorescent protein; YFP = yellow fluorescent protein). CFP is excited by 435 nm light and emits lights at 480 nm. YFP is excited by 480 nm light and emits light at 535 nm. 400 500 Wavelength of Emitted Light 400 500 Wavelength of Emitted Light 600 600 Fluorescence 400 400 500 Wavelength of Emitted Light 600 500 Wavelength of Emitted Light 600 Fluorescence Intensity 400 500 Wavelength of Emitted Light 600 Figure Legend.
