Identify the following membrane-associated proteins based on their structure: (a) tetramers of identical subunits, each with six membrane-spanning $\alpha$ helices; (b) trimers of identical subunits, each with $16 \beta$ sheets forming a barrellike structure.

Q9. Here is a diagram of 300-residue plasma membrane protein. It is not a channel or transporter, but it does contain 3 transmembrane helices (H1, H2 & H3). The N and C-termini are labelled as are the start and end of each transmembrane helix. There is a folded domain (shown as an ellipse) between H2 and H3. An N-glycan is shown as a hexagon. Which statement best describes this protein? The transmembrane helices are of the expected length. The transmembrane helices will exhibit heptad repeat patterns. The N-terminus is extracellular. The folded domain is likely to contain disulphide bonds.
