Draft:Osmosensing transporter

An osmosensing transporter or osmosensory transporter is a type of biological membrane protein, whose function in a cell is to detect the cell's osmotic pressure and facilitate cellular responses to maintain the cell's volume. Osmosensory transporters play an essential role in cell functioning as they are a critical component of cellular osmoregulation, maintaining cellular homeostasis and supporting a range of critical cell functions. They are different from osmosensors because, although osmosensors and osmosensing transporters are both involved in detecting osmotic stress, osmosensors are not directly involved in facilitating the movement of molecules across the cell membranes.
