Protein
Small-conductance mechanosensitive channel
Organism
Caldanaerobacter subterraneus subsp. tengcongensis (strain DSM 15242 / JCM 11007 / NBRC 100824 / MB4)
Function
Mechanosensitive ion channel that participates in the regulation of osmotic pressure changes within the cell, opening in response to stretch forces in the membrane lipid bilayer, without the need for other proteins. Has high selectivity for anions, and may contribute to resistance to hypoosmotic shock.
Similarity
Belongs to the MscS (TC 1.A.23) family.
