Protein Recycling

Recycling is important not only on a global scale, but also at the cellular level, since key molecules tend to be available in limited numbers. This means a cell needs to have efficient recycling mechanisms.Certain intercellular proteins are needed to respond to specific extracellular signals. This movie covers how such proteins can be stored, recycled and kept available during the periods of time in between the arrival of such extracellular signals.
