General description
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.

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.
Nanodisc soluble lipid bilayer systems have proven to be a widely applicable means for rendering membrane proteins soluble in aqueous solutions in a native-like bilayer environment where they remain monodisperse and active. The critical component of nanodiscs is the encircling amphipathic helical protein belt (membrane scaffold protein).
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.
Biochem/physiol Actions
Generates Nanodiscs ~9.7 nm in diameter
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.[1]

Carotenoids are a core plastid component and yet their regulatory function during plastid biogenesis remains enigmatic. A unique carotenoid biosynthesis mutant, carotenoid chloroplast regulation 2 (ccr2), that has no prolamellar body (PLB) and normal PROTOCHLOROPHYLLIDE OXIDOREDUCTASE (POR) levels, was used

Diverse soil-resident bacteria can contribute to plant growth and health, but the molecular mechanisms enabling them to effectively colonize their plant hosts remain poorly understood. We used randomly barcoded transposon mutagenesis sequencing (RB-TnSeq) in Pseudomonas simiae, a model root-colonizing bacterium

Macroautophagy/autophagy is a conserved process in eukaryotes that contributes to cell survival in response to stress. Previously, we found that endoplasmic reticulum (ER) stress induces autophagy in plants via a pathway dependent upon AT5G24360/IRE1B (INOSITOL REQUIRING 1-1), an ER membrane-anchored
