摘要

蛋白质-蛋白质相互作用在真核生物的各项生命活动中发挥重要作用。与其它蛋白质互作研究技术相比, 借助于烟草(Nicotiana benthamiana)瞬时表达系统的萤火素酶互补实验(LCA)具有简单、灵敏、可靠、高效和低背景等优点, 并可轻松扩展为大规模蛋白质互作的筛选和验证研究。该文介绍了萤火素酶互补实验的具体操作过程, 通过2种数据收集方法来定性并定量分析生物发光或发光强度, 从而检测植物目标蛋白之间的相互作用。

Abstract

Protein-Protein interactions play important roles in various eukaryotic biological processes. Compared to other techniques measuring protein-protein interactions in plants, the Luciferase Complementation Assay (LCA), based on Agrobacterium-mediated transient expression in Nicotiana benthamiana, is a simple, sensitive, reliable, highly quantitative and low background method that can be easily scaled up for high-throughput interactome studies. Here, we describe a protocol that includes two alternative data collection methods to qualitative and quantitative analyse luminescence or luminous intensity to detect protein-protein interactions in plant cells.
