Active cellular water pump for osmoregulation.
Unicellular organisms in fresh water need to actively pump water out to balance the large flux of water coming in due to osmotic pressure difference. No molecular water pumps are known, so this water pump must be supramolecular.

How do cells maintain a constant protein density during growth, although the protein content is very small (1% in number of that of other osmolytes) and does not directly control cell volume? Why does density homeostasis break down at senescence, and transiently at mitotic entry?
