Questions

Yоu wоrk in а lаb dedicаted tо characterizing the physiology of a mammalian ligand-gated potassium channel (functions as an oligomer, ligand is PIP2). The channel has several post-translational modifications that regulate stability and function. You decide you want to solve the structure. 1. (4pts total) Before you solve the structure, you want to understand the protein topology. The sequence of the protomer has two membrane-spanning transmembrane helices. With the below sequence, please enclose likely TM domains in [brackets] (2pt). Also, please enclose loop(s)/tail(s) that are likely cytoplasmic facing in (parentheses) (2pts).  MKKSRVRKYA SVAVITLVPM LSFAIFWEGD DPAKAAFNSL QASATEYIGYAWAMVVVIVG ATIIYKLFKK FTSKAS   2. (2pts) Another lab found a well-behaved protein with similar physiological function in Aspergillus fumigatus (a fungus) that has 42% sequence identity. Would solving the structure of this protein likely inform understanding of the structure of mammalian protein? Why or why not? 3. (8pts total) Propose a workflow to generate the purified mammalian channel (4pts, 1pt per step), provide a specific example and your rationale at each step. How could you determine if the purified protein is likely in the native state (2pt)? Describe two ways you could try to optimize potential issues in your purification workflow (such as instability, impure protein, misfolding) (2pt).  

Chооse оne (1) prompt аnd write а well-orgаnized essay in response. Your essay should be about 300-400 words, be organized around a thesis statement, and use a minimum of three (3) specific examples to support your argument. Discuss the influence of the image of Alexander during the Hellenistic period, both in regards to imitations as well as the use of depictions of the man himself. What is our evidence for painting in Ancient Greece? What do we use to reconstruct what we have lost and how? You have decided to excavate a Greek house. What do you expect to find? Describe the architecture, layout, and content of a typical Greek house. What conclusions can we draw from the archaeological evidence about the daily lives of the Greeks and their activities in the house?
