摘要:

14-3-3蛋白是由不同基因编码的高度同源的酸性蛋白质家族,在真核生物中广泛存在,且在结构上相对保守。14-3-3蛋白主要是通过识别靶蛋白上的磷酸化位点与靶蛋白发生相互作用,导致靶蛋白的稳定性、亚细胞定位或与其他蛋白之间的相互作用发生显著变化,进而调控靶蛋白的功能。不同物种中含有多种亚型的14-3-3蛋白,这些不同的亚型蛋白通过与其他蛋白的相互作用来影响植物的生长发育等过程。本文概述了14-3-3蛋白在植物中的种类、亚细胞定位以及在组织中的表达情况,重点总结了14-3-3蛋白在植物激素信号转导、生长发育及胁迫响应中的功能,以期为今后系统开展14-3-3蛋白的研究提供理论依据。

Abstract:

14-3-3 proteins are a highly conserved family of acidic proteins encoded by different genes in eukaryotic organisms. After interacting with the target proteins through the phosphorylation sites, 14-3-3 proteins influence the stability, subcellular localization, or interactions with other proteins of the target protein, thereby regulating its function. Various isoforms of 14-3-3 proteins have been found in different species, and these isoforms influence the processes such as plant growth and development. In this review, we summarize the type, subcellular localization, and expression patterns of 14-3-3 proteins in plants, with a specific focus on the functions of 14-3-3 proteins in plant hormone signaling, growth and development, and stress response. The aim of this review is to provide a theoretical foundation for further systematic research on 14-3-3 proteins.

Key words: 14-3-3 proteins, hormone signaling, growth and development, stress response
