The proteins that a cell is making at a given time can help us understand what the cell is doing or if it isn’t functioning properly and like I said before, this is really valuable information. Internal signaling proteins basically play a game of telephone to transmit that signal down to the nucleus, and the cell can respond to its environment by making new proteins or even breaking down proteins that are already present into their amino acid subunits. Receptor proteins on the surface of a cell allow it to understand what is happening in the local environment. So, learning about the internal workings of a cell is a really important task, and at the heart of all of these processes are proteins which are the “doers” of the cell. If they know how cells work on the inside, they can use this information to better treat, or potentially cure a wide range of diseases. For a cell to be able to accomplish important tasks like these, there is a lot that has to happen within the membrane, and scientists are really excited about uncovering what all of those internal cellular processes are.
