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.

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.

생화학적/생리학적 작용

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.
