植物细胞中的RGD模体及受体

Arg-Gly-Asp(RGD)模体是动物细胞底物黏附分子的基本识别结构,许多胞外黏附蛋白是通过RGD模体与质膜受体整合素结合的,它参与细胞的跨膜信号转导,介导多种生物学过程。越来越多的实验表明植物细胞中也存在RGD结合模体,现就近年来植物细胞在这方面的研究进展进行综述。

RGD Motif and Receptor in Plant Cell

The sequence Arg-Gly-Asp (RGD) is the essential structure recognised by animal cells in substrate adhesion molecules. It is generally thought that the interaction between plasma membrane-bound recep- tors known as integrins and extracellular adhesive proteins is mediated through the RGD motif, which involved in transmembrane signaling and many physiologic process. The recent discovery suggests that this type of interaction may be widespread in the plant kingdom. The advance in RGD motif and its receptor research for plant cell was reviewed.
