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 MSP1E3D1 variant of MSP1 differs from MSP1 in the following facets: It deletes the first 11 amino acids in the Helix 1 portion (referred to as “H0.5” in the accompanying figure) of the original MSP1 sequence3 (which is known separately as MSP1D1). It repeats the Helix 4 (H4), Helix 5 (H5) and Helix 6 (H6) sequences of the original MSP1 sequence between the parent Helix 6 (H6) and Helix 7 (H7) segments of MSP1D1.

應用
纳米盘可溶性脂质双层系统已被证明是一种广泛适用的手段，用于使膜蛋白溶在水溶液中的类似天然的双层膜环境中，维持其单分散和活性。纳米盘的关键组分是包绕着两亲性螺旋蛋白质带（膜支架蛋白）。
纳米盘系统已被用于包裹多种蛋白质，包括 GPCR、P450、细菌视紫红质、凝血因子、霍乱毒素、TAR 受体和芳香酶。
