Structural Classification of Proteins

Family: Ligand-gated protein channel

: monomeric (22,24) barrel; ~150 N-terminal residues form a "plug" or "cork" subdomain

Lineage:

Root: scop

Does not include proteins in the immune system
Fold: Transmembrane beta-barrels [56924]
not a true fold, gathers together transmembrane barrels of different (n,S)
Superfamily: Porins [56935]
uperfamily
Family: Ligand-gated protein channel [56948]
