Yоu аre studying а prоtein yоu cаll Unknown Protein 1 or UP1 in rat neurons. You believe mutations in UP1 may predispose people to Parkinson's Disease, so that wildtype UP1 may be neuroprotective. You have a rat model for Parkinson's Disease (PD rats), and you can culture neurons from PD rats and see markers of Parkinson's Disease. To test your neuroprotective hypothesis, you want to express wildtype UP1 in PD rat neurons. a. Starting with the UP1 protein sequence, name the procedure you will use to isolate a DNA fragment encoding UP1? b. How will you use the DNA from part a to express wildtype UP1 in cultured PD rat neurons (what do you need to do with the DNA from part a)? c. You raise an antibody against UP1. You want to use this antibody to: 1) identify the band on a PAGE gel that contains UP1 protein, and 2) visualize the localization of UP1 protein within PD rat neurons. Is it possible to perform both of these approaches with this antibody? Provide a brief explanation of why (or why not).
