A mechanosensitive ion channel called TACAN was recently reported. We began to study TACAN with the intent to understand how it senses mechanical forces and functions as an ion channel.
WebIon-channel-linked receptors have a large membrane-spanning region which enables them to create a channel.Most of the amino acids in the membrane-spanning region are hydrophobic, so they are able to interact with the phospholipid fatty acid tails that make up the center of the plasma membrane.On the other hand, the amino acids that line the …
