Mechanosensitive channels
Mechanosensitive channels, mechanosensitive ion channels or stretch-gated ion channels are membrane proteins capable of responding to mechanical stress over a wide dynamic range of external mechanical stimuli. They are present in the membranes of organisms from the three domains of life: bacteria, … See more Mechanosensitive channels were discovered in 1983 in the skeletal muscle of embryonic chicks by Falguni Guharay and Frederick Sachs. They were also observed (pub. 1986) in Xenopus oocytes, and frequently … See more For a protein to be considered mechanosensitive, it must respond to a mechanical deformation of the membrane. Mechanical deformations can include changes in the … See more Although MS vary in many aspects, structures and functions, all the MS studied to date share an important feature: in a process called gating, they all open in a pore-like manner … See more In eukaryotes, two of the best known mechanosensitive ion channels are the potassium channels TREK-1 and TRAAK, both of which are … See more MS can be classified based on the type of ion to which they are permeable.
