Depletion of cholesterol in the cell membrane using a drug (mevastatin) has been associated with apoptosis in cancer cells. a. What effect would cholesterol depletion have on the integrity of lipid rafts in the membrane? b. Researchers found that FAS death receptor was activated in cholesterol depleted cancer cells. Explain how activation of this receptor activates killer caspases. c. When a caspase is converted from its inactive to its active form there are changes in the primary and tertiary structure...

2. You have isolated a protein from sperm that you suspect is involved in binding to the zona pellucida and triggering the acrosome reaction. You generate an antibody to this protein and use the antibody to isolate the protein. You have obtained peptide information and used this peptide data to identify the DNA sequence that encodes your protein of interest. a. What zona protein do you suspect this sperm protein binds to? b. What expression pattern is consistent with your...
