Each monomer consists of a N-terminal transmembrane region and a large cytoplasmic segment composed of a five-stranded antiparallel beta-sheet (middle/second) domain and a C-terminal alpha/beta-domain [4-7]. This is the beta domain which adopts a Sm-like barrel structure.

These channels open in response to stretch forces in the membrane lipid bilayer and control plastid size, shape, and perhaps division during normal plant development by altering ion flux in response to changes in membrane tension [1]. They act as a component of the chloroplast division machinery [2]. These channels are closely related to MscS from bacteria.
