一般說明
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.
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方法，用于呈现膜蛋白可溶于水溶液中，在类似原生的双层环境中保持单分散和活性。纳米盘的关键组成部分是环绕的两亲性螺旋蛋白带（膜支架蛋白）。
纳米盘系统已经被用于包括 GPCRs 、P450 、细菌视紫红质 、凝血因子 、霍乱毒素 、焦油受体 和芳香化酶 等多种蛋白质的掺入。

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
