General description

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 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.

Application

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.
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.

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

Autophagy is a conserved catabolic process in eukaryotes that contributes to cell survival in response to multiple stresses and is important for organism fitness. In Arabidopsis thaliana, the core machinery of autophagy is well defined, but its transcriptional regulation is
