在最近发表的工作中，我们确定了第一个叶绿体定位的E3连接酶，并表明它通过泛素-蛋白酶体系统（UPS）降解TOC转位蛋白。这种调节被发现是至关重要的质体发育的转变，如转换的病原体叶绿体。本文讨论了SP1在不同环境下对植物的重要性，并对SP1的功能及其在农业上的应用进行了展望。我们预计，在这一领域的进一步工作可能会揭示UPS系统的其他作用，通过对其他叶绿体OEP与质体生物发生和功能的不同作用的行动。
In a recently published work, we identified the first chloroplast-localized E3 ligase, and showed that it degrades TOC translocon proteins by the ubiquitin-proteasome system (UPS). This regulation was found to be critical for plastid developmental transitions, such as the conversion of etioplasts to chloroplasts. Here we discuss the importance of SP1 for plants under different circumstances, and speculate about SP1 function and its possible application in agriculture. We anticipate that further work in this area may reveal additional roles of the UPS system, through action on other chloroplast OEPs with different roles in plastid biogenesis and function.
