| 摘 要： | 受体是研究生长素信号传导链的关键环节,因为只有生长素与生长素受体结合以后才会引起后续的级联反应,生长素受体的发现对探索和了解生长素调控机制是极其重要的.目前所发现的生长素结合蛋白(受体)有TIR1和ABP1.扼要的介绍生长素受体TIR1的结构及其与生长素的结合位点,阐述了TIR1在基因水平上的调控和AUX/IAA被泛素化后最终被26S蛋白酶体降解的过程.概述了ABPI的结构、活性位点、性质以及ABP1的作用机理的模型.

| Abstract: | The receptor of auxin play a key role in signal transduction,the binding of auxin with its receptor could cause cascade reaction.In order to explore and understand auxin regulation mechanism,it is extremely important to study auxin receptor.Currently, TIRl and ABPl have been found in auxin receptor family.This paper introduced the structure of TIRl,the binding sites with auxin, TIRl regulation on the gene level,AUX/IAA ubiquitination and the process being degraded by 26S protease body.The ABPl structure, ac... |
