Application

Membrane Scaffold Protein 1D1 has been used as a scaffolding protein to stabilize lipid nanodiscs (NDs). It has also been used for the preparation of nanodiscs.

For guidelines on the use of this and other MSP′s to prepare Nanodiscs, please visit our Protocols for Membrane Scaffold Proteins and Nanodisc Formation page.

Nanodisc soluble lipid bilayer systems have proven to be a widely applicable means for rendering membrane proteins soluble in aqueous solutions in a native-like bilayer environment where they remain monodisperse and active. The critical component of nanodiscs is the encircling amphipathic helical protein belt (membrane scaffold protein).

The nanodisc system has been employed to incorporate a wide variety of proteins including GPCRs, P450s, bacteriorhodopsin, coagulation factors, cholera toxin, TAR receptor and aromatase.

Biochem/physiol Actions

Generates Nanodiscs ~9.7 nm in diameter

Membrane scaffold protein 1D1 (MSP1D1) is derived from apolipoprotein A-I. It is an amphipathic synthetic protein, which self assembles to form nanodiscs.[1]

Physical form

Supplied as a lyophilized histidine-tagged protein with a TEV protease cleavage site stabilized with Tris-HCl, EDTA, and NaCl.
