General description

Facade®TEM/FA-4 (3α,7α,12α-tri-((O-β-D-maltopyranosyl)ethyloxy)-cholane) is a sterol-based/sugar-based facial amphiphile. It carries three sugar attachments on the steroid backbone.

Biochem/physiol Actions

Facade®TEM/FA-4 (3α,7α,12α-tri-((O-β-D-maltopyranosyl)ethyloxy)-cholane) can be used in the preparation of micelles. It may also be used in the stabilization and crystallization of membrane proteins. FA-4 is not effective as a cystic fibrosis transmembrane conductance regulator (CFTR) solubilizer.

Amphiphile selection is a critical step for structural studies of membrane proteins (MPs). We have developed a family of steroid-based facial amphiphiles (FAs) that are structurally distinct from conventional detergents and previously developed FAs. The unique FAs stabilize MPs and...
