A heat shock protein increases in abundance after exposure to 40°C compared to 24°C. You can visually see the increase in band intensity on a Western blot. You treat your cells with MG132 to block the activity of the proteasome as well as treating the cells with antinomycin to block transcription. Looking at your Western blot, the protein abundance of the heat shock protein decreases over time at the same temperature. What is the most likely reason for this observed decrease?
