摘要
植物脂质转运蛋白(Lipid transfer protein,LTP)是一类小分子碱性蛋白,占植物可溶性总蛋白的4%左右,目前已经在许多植物中克隆了LTP的编码基因。LTP是一种多功能的蛋白,除了被认为参与了磷脂在生物膜之间的运输外,LTP还在生物膜、角质和脂质的形成、植物的生殖发育以及信号的转导等生物过程中发挥了重要的作用,另外LTP作为一种食物过敏原和防御蛋白引起了科研人员越来越多的兴趣。本文综述了LTP的生物学功能,对LTP在农业上的应用前景做了展望。
Plant lipid transfer proteins(LTPs) are a group of small basic protein, accounting for 4% of the total soluble proteins. The genes encoding LTPs have been cloned in various plants. LTPs are muhifunctional proteins involved in phospholipid transfer between membranes, formation of cutin and lipid. They also play important roles in plant reproduction and signal transduction. As an allergen and defensive protein, LTPs caused the interest of many researchers. This article summarized the biological functions of LTPs and discussed its application in agriculture.
