MscS and MscL are mechanosensitive channels that ... O open at the same osmotic pressure, but differ in their ion selectivity. All of these statements describe MscS/MscL. O open in response to membrane tension. O are highly ion selective. O constitute the majority of channel proteins in the plasma membrane of auditory hair cells in the human cochlea.

Step 1
Mechanosensitive ion channels are one example of a subset of proteins that translate mechanical signals into a biochemical response. The two major mechanosensitive channels are MscS (mechanosensitive channel small conductance) and MscL (large conductance) and both have very large conductances, or pore sizes, relative to eukaryotic channels.
