A prototype signal protein and its receptor is illustrated here.
The human body relies on hundreds of different signal proteins docking
into very specific and selective cell membrane receptor proteins to
control which cell proteins are made or broken down and how the cell
functions by sending specific chemical signals to other parts of the
cell. The signal proteins may be produced by a nearby cell or reach
its target from a distant cell through the blood stream.
cells work correctly just about each and every day can seem even
more remarkable.
Over many decades, scientists have worked to understand how
each of these systems in each cell and in the whole organism
