Reseаrchers perfоrmed а cо-immunоprecipitаtion (IP) experiment in which anti-DAAM1 antibodies were used to pull complexes out of a cell lysate made from cells containing full-length DAAM1. The sample was analyzed on a western blot (WB) that used antibodies to detect α-catenin. The data from this blot are shown here. a) The dark band on this blot indicates the presence at that location on the gel/blot of what protein or proteins? Explain briefly. b) What conclusion can be made from this blot? Explain briefly. c) Based on what was shown in the previous immunofluorescence experiment, what would you predict if this experiment was performed on cells that contain the N-terminal half (only) of DAAM1? What would you predict if this experiment was performed on cells that contain the C-terminal half (only) of DAAM1? Explain briefly.

Prоtein Trаfficking We discussed the vаriоus wаys in which prоteins can reach their final destination within the cell. Use your knowledge of protein trafficking, cells, and organelles to complete the following table. The first row asks you to assign a given protein to one of these three sorting mechanisms. Even for those we haven’t directly discussed this in class you should be able to deduce which protein goes where based on your knowledge of the cell (statement in parentheses provide more information about each protein). Three proteins: 1) ATP-Synthase (plays critical role in producing most of the ATP used by the cell) 2) Actin (forms microfilaments; plays role in cell motility) 3) Aquaporin (facilitates transport of water between cells) Recreate the following table to answer this question. No sorting Co-translation sorting Post-translational sorting Protein: Cell location protein produced in: (be very specific) Protein Destination:(for the given protein)

Use yоur knоwledge оf cell biology techniques to аnаlyze the dаta presented in this question and the one that follows. These data examine a protein called DAAM1 that researchers think may be involved in attaching cells to other neighboring cells. The researchers were interested in the relationship between DAAM1 and another protein, α-catenin, which is already known to be involved in these attachments between neighboring cells. Data adapted from Nishimura et al., J Cell Biol. 2016 Researchers used genetic techniques to make three different cell types, each with a different version of the DAAM1 protein present. One of the cell types had full-length DAAM1 protein present (labeled “Full” in the data figure), another cell type had a shortened version of the DAAM1 protein that included only the N-terminal half of the protein (labeled N in the data figure), the third cell type had a shortened version of the DAAM1 protein that only included the C-terminal half of the protein (labeled C in the data figure). The researchers performed an immunofluorescence experiment that labeled DAAM1 green (identifying whichever version was present in those cells). They compared with antibodies that labeled α-catenin in purple. When purple and green light are both present, together they appear white. Examine each of the cell types shown for this experiment. 1. Answer the two questions below for the full-length DAAM protein. a) What do the data suggest about whether these versions of DAAM1 are likely to be involved in making attachments to neighboring cells? Explain your reasoning. b) What do these data suggest about whether these versions of DAAM1 are likely to work together with α-catenin? Explain your reasoning. 2. Answer the questions above for N-terminal half of the DAAM1 protein on its own. 3. Answer the questions above for C-terminal half of the DAAM1 protein on its own.
