Mechanosensitive channels

by اسراء عمار معروف ابو صنوبر _ - Monday, 21 February 2022, 6:34 PM

They are present in the membranes of organisms from the three domains of life: bacteria, archaea, and eukarya.They are the sensors for a number of systems including the senses of touch, hearing and balance, as well as participating in cardiovascular regulation and osmotic homeostasis (e.g. thirst). The channels vary in selectivity for the permeating ions from nonselective between anions and cations in bacteria, to cation selective allowing passage Ca²⁺, K⁺ and Na⁺ in eukaryotes, and highly selective K⁺ channels in bacteria and eukaryotic.
