In аdditiоn tо Menа аnd Lpd, discussed in class, there are many оther proteins that have also been shown to play a role in cell migration. The research described in this question (and published: J Cell Biol. 2013 Nov 25; 203(4): 673–689) explored whether Lpd and another regulator of the cytoskeleton, a protein called Scar, are working in a coordinated way in cell migration or whether they function independently. The researchers performed an experiment in which they immunoprecipitated Lpd-containing complexes out of cell lysates and used the material they obtained to perform a western blot with antibodies that bind to Scar. The data are shown here. a) What is the conclusion from this experiment? Explain briefly b) What does the band in this figure represent? Explain briefly Next the researchers generated mouse embryonic fibroblast cells (MEFs) in which the gene encoding Lpd was deleted completely. These cells are referred to here as “Lpd KO” because KO is an abbreviation for “knock out.” They compared these MEFs with wild-type cells that have all their genes intact. These are referred to as “WT MEFs”. The researchers took the WT MEFs and Lpd KO MEFs and created cell lysates of each cell type separately. They used these cell lysates for western blots with antibodies that bind to Scar. The data are shown here. c) What is the conclusion from this experiment? Your answer should refer to both Lane 1 and Lane 2. Explain briefly. d) In this experiment, if there had been a band in Lane 1 but not in Lane 2, what would the conclusion have been from the experiment? Explain briefly. Make sure to label the parts of your answer a-d to facilitate grading.
