Step by step
Solved in 2 steps
- 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.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 GEFUsing examples, describe the signalling pathway from receptor tyrosinekinase activation to gene transcription, highlighting key phosphorylationevents and domains involved
- Describe e-cadherins' ligand affinity properties. What is e-cadherins' role in cell sorting? Have detail.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 bindingProvide three examples of some enzyme-coupled receptors bypass intracellular signaling cascades to regulate gene transcription.
- Explain the role/importance of the localization of GTPase-activating protein (Ran-GAP) in BOTH nuclear export and import. What would occur if there was a loss of function mutation in Ran-GAP? What would occur if Ran-GAP was localized in the nucleus?Explain the role/importance of the localization of GTPase-activating protein (Ran- GAP) in BOTH nuclear export and import. What would occur if there was a loss of function mutation in Ran-GAP? What would occur if Ran-GAP was localized in the nucleus?The oscillatory clock that drives somite forma-tion in vertebrates involves three essential componentsHer7 (an unstable repressor of its own synthesis), Delta (atransmembrane signaling molecule), and Notch (a trans-membrane receptor for Delta). Notch is bound by Delta onneighboring cells, activating the Notch signaling pathway,which then activates Her7 transcription. Normally, thissystem works flawlessly to create sharply defined somites(Figure Q21–2A). In the absence of Delta, however, onlythe first five somites form normally, and the rest are poorlydefined (Figure Q21–2B). If a pulse of Delta is suppliedlater, somite formation returns to normal in the regionswhere Delta was present (Figure Q21–2C). A diagram ofthe connections between the components of the clockand how they interact in adjacent cells is shown in FigureQ21–2D. In the absence of Delta, why do the cells becomeunsynchronized? What is it about the presence of Deltathat keeps adjacent cells oscillating in synchrony?
