Research area: Cell signaling. Nanodiscs are non-covalent structures that contain a phospholipidbilayer and a membrane scaffold protein (MSP), a genetically engineeredprotein, that mimics the function of Apolipoprotein A-1 (ApoA-1). The firstMSP, MSP1, was engineered with its sequence based on the sequence of A-1, butwithout the globular N-terminal domain of native A-1. The Membrane ScaffoldProtein 1D1 (MSP1D1) variant of MSP1 deletes the first 11 amino acids in theHelix 1 portion (referred to as “H0.5” in the accompanying figure) of theoriginal MSP1 sequence.It consists of an N-terminal histidine-tagged protein with a tobaccoetch virus (TEV) protease cleavage site that is present between the proteinsequence and histidine-tag.Nano-disctechnology is an approach that allows aqueous soluble membrane proteins in anative-like bilayer environment that enables the membrane proteins to remainactive and stable.
