4. You have discovered a novel plasma membrane protein that you think is a receptor for rose smell in bees. You obtain its amino acid sequence and determine that a full-length precursor of this protein can be divided into five regions (a-e in the diagram below; N and C indicate amino and carboxy termini). Your biochemical analysis shows that regions b and d are comprised of hydrophobic amino acids and likely serve as internal start and stop transfer sequences for co-translational insertion into the membrane of the endoplasmic reticulum. Using this knowledge, answer the questions below. (3 points each, 9 points total) a b C d e N A. When this receptor appears on the plasma membrane, is the N terminus of this protein located in the cytoplasm or outside of the cell?_ B. How about its C terminus? (in the cytoplasm or outside?). C. Which region(s) of this protein is (are) most likely to glycosylated?
