Beschreibung

Allgemeine Beschreibung

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.

Anwendung

Das Nanodisc-System wird zum Integrieren einer Vielzahl von Proteinen, einschließlich GPCRs, P450s, Bacteriorhodopsin, Gerinnungsfaktoren, Choleratoxin, TAR-Rezeptor und Aromatase, eingesetzt.

Nanodiscs mit löslichen Lipiddoppelschichten werden in vielen Anwendungen eingesetzt, um Membranproteine in wässrigen Lösungen in einer naturgetreuen Doppelschicht, in der sie ihre Monodispersität und Aktivität aufrechterhalten, löslich zu machen. Die wichtigste Komponente der Nanodiscs ist der umschließende amphipathische helikale Proteingürtel (Membran-Gerüstprotein).

Biochem./physiol. Wirkung

MSP1D1 can self-assembleinto discoidal nanoparticles known as nano-discs. These nano-discs may be used inthe field of medicine, biotechnology, and membrane protein studies.
