Opis

Opis ogólny

Nanodisc technology is an approach to render membrane proteins soluble in aqueous solutions in a native-like bilayer environment, where the membrane proteins remain stable and active. The Nanodisc concept is derived from high density lipoprotein (HDL) particles and their primary protein component, apolipoprotein. The Nanodisc is a non-covalent structure of phospholipid bilayer and 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. The MSP1ΔW variant of MSP1D1, sometimes referred to as “Dark MSP”, replaces the two tryptophan (W) residues in the parent MSP1D1 sequence with phenylalanines (F). These two (W→F) substitutions are at the following positions of the original native A-1 sequence:

• Position 72, within the Helix 2 (H2) segment
• Position 108, within the Helix 4 (H4) segment
