Environmental stimulus Sensor. protein Response- regulator The sensor protein spans the cytoplasmic membrane. The response regulator is a protein inside the cell. P In response to a specific change in the environment, the sensor phosphorylates a region on its internal portion. The phosphate group is transferred to the response regulator, which can then turn genes on or off, depending on the system. FIGURE 7.19 Two-Component Regulatory System

true or false? And why it is false For the actin cytoskeleton, diverse cell-surface receptors trigger global structural rearrangements in response to external signals. But all these signals seem to converge inside the cell on a group of closely related monomeric GTPases that are members of the Rho protein family—Cdc42, Ras, and Rho. The same Rho family proteins are also involved in the establishment of many kinds of cell polarity.
Part A (Short Response): You are developing a TGF-β agonist, but you don’t yet know which specific proteins it is signaling through. You want to do a single Western blot to measure changes in signaling activity, regardless of which pathway is being activated. For which protein involved in these pathways could you measure the levels in the nucleus of cells and be confident in your results? Why? This part was already posted on chegg, but I didn't understand the answer. I need a thorough explanation, so I can fully understand. Part B (Short Response): There have been many attempts to block TGF-β signaling in cancer through many different mechanisms, but none of been very successful. Why do you think this is? I know they have gotten close to being successful, but I don't know what preventing their success.
Ras uses proteins called ___________________ proteins. These proteins bridge the receptor and Ras (small monomeric G-protein) and induce Ras to release GDP and bind GTP which makes the Ras active. Active Ras can initiate a kinase cascade.

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 GEF
Cell signaling. The ER doctors gave a patient an injection of epinephrine to increase his heart rate and blood pressure. The heart rate and blood pressure went up but not enough. The second dose of the same drug seemed not to have an effect. What do you think may be a possible explanation for this result?
