This alignment represents a conserved transmembrane helix, often found in small conductance mechanosensitive channels (MscS) in association with Pfam:PF00924 [1-3], such as Swiss:Q57634 and Swiss:Q58543 MscS assembles to a homoheptameric complex; 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 (Pfam:PF00924) and a C-terminal alpha/beta-domain (Pfam:PF21082) [1-3]. The N-terminal region consists of three membrane spanning helices (TM1, TM2 and TM3), TM1 is represented in this entry. In the heptamer, the permeation pathway is formed by the packing of TM3s, flanked by TM1-TM2 helical hairpins [1-3]. [1]. 23339071.

This entry includes small conductance mechanosensitive channels (MscS), which assembles to a homoheptameric complex [1-6]. 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 SH3-like barrel structure. [1]. 11296222. Structural and functional differences between two homologous. mechanosensitive channels of Methanococcus jannaschii..
