MSP1T2 Usage And Synthesis

Uses

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.

Uses

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.

General Description

Nanodiscs are non-covalent structures that contain a phospholipid bilayer and a membrane scaffold protein (MSP), a genetically engineered protein, which mimics the function of Apolipoprotein A-1 (ApoA-1). The first MSP, MSP1, was engineered with its sequence based on the sequence of A-1, but without the globular N-terminal domain of native A-1. The Membrane Scaffold Protein 1D1 (MSP1D1) variant of MSP1 deletes the first 11 amino acids in the Helix 1 portion (referred to as “H0.5” in the accompanying figure) of the original MSP1 sequence.

Biochem/physiol Actions

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