1) Amino acids that contain hydroxyl groups in their R-groups can be phosphorylated during cellular signaling. (a) What amino acids can be phosphorylated? (use the one letter amino acid abbreviations) (b) Does phosphorylation turn a signaling protein “on” or “off”? (c) Whatis the most common source of a phosphate used to phosphorylate a protein (d) What enzyme type (or category of enzymes)removes phosphates from proteins?
Yeast cells are eukaryotes, and they require a functional secretory pathway to grow and to maintain cellular organization. But surprisingly, when SRP is removed from yeast cells by deleting the relevant genes, the cells are still alive (although they grow slowly). a) How can yeast survive without SRP? Propose two alternative hypotheses. b) How might electron microscopy of normal and SRP-deficient yeast cells help you to distinguish between these two hypotheses?
If you wanted to engineer the initiator caspase from the Fas/FasL extrinsic apoptosis pathway to function in the intrinsic pathway (e.g. in response to DNA damage), which of the following would be the most likely approach to succeed? O Replace the extrinsic pathway's initiator caspase Death Effector Domain with a CARD domain O Replace the Fas Death Domain with a cytochrome C binding domain O Generate a version of the Fas receptor that localizes to the mitochondrial intermembrane space 80 O Replace the intrinsic pathway's initiator caspase CARD domain with a Death Effector Domain F3 0 $ 4 DOD DOO R F4 S % 5 T No new data to save.

The following statements about the 'membrane attack complex' (MAC) is incorrect. Explain (i) The structure of the MAC is different for both classical and alternative pathways. (ii) C9 is activated due to cleavage by C8.
Which of the following dephosphorylates PI 3,4,5-trisphosphate, thereby blocking the activation of PKB/Akt?
Which of the following is true about chromodomains? a) bind methylated histone tails b) are associated with repression c) both a and b d) none of the above
Aberrant signaling through the Ras-BRaf-MAPK signal transduction pathway drives many cancers. This makes the pathway an attractive drug target, and many small molecules have been developed that target either Ras, BRaf or MAPK. In malignant melanoma, one mutation in particular, where valine 600 of Braf is mutated to a glutamic acid (V600E), is found in the majority of cases. This mutation makes BRaf activation independent of upstream Ras activity. Would a small molecule that targets Ras be effective in a melanoma case driven by Braf V600E? Explain your answer.
Notch is an important transmembrane receptor that is present on the plasma membrane. Curiously, it possesses a proteolytic cleavage site and an NLS in its intracellular domain. In a protein fragment complementation experiment the Notch receptor was fused to the N-terminal portion of GFP on its intracellular domain. Another protein that is known to act in the nucleus to mediate the Notch signal following its activation was fused to the C-terminal region of GFP. When both are expressed in the same cell, GFP is observed in the nucleus. In 3-4 sentences provide an explanation that would account for the expression of GFP exclusively in the nucleus.
When Hedgehog binds to Patched, this not only activates the signaling pathway but alsoactivates the receptor-mediated endocytosis of Patched, so there is less Patched on the plasmamembrane to inhibit Smoothened. a. Outline the steps of receptor-mediated endocytosis, including the roles for each proteininvolved. Hint: if your answer does not include the protein dynamin, you are notproviding enough detail. b. What will happen to Patched after it enters the cell via receptor-mediated endocytosis?Assume that Patched is not recycled back to the plasma membrane.
), create a simple flowchart depicting the MC1R pathway. There should be a minimum of five steps in the pathway. Be sure to include reception (protein binding to its ligand), a portion of the transduction pathway (what’s the intracellular reaction? What molecule works intracellularly?), and the cellular response (What’s produced from the cell?).
The Pathway presented shows you how the pathway is regulated with a Ras-GEF. Explain how adding a Ras-GAP to the cell would A) specifically affect the molecules of the signaling pathway and B) affect the response of the cell.
Researchers use a technique call RNA interference to knock down (i.e. not completely gone) the Bcl-2 gene in the amygdala of lab animals. What cellular response would you expect to occur? Question 1 options: A) An increase in apoptosis; many cells in the area would die B) An increase in axon regrowth after injury C) A decrease in cytochrome c levels released from the mitochondria D) A decrease in glial cell infiltration after injury
