细胞必须根据细胞状态和环境动态调节过氧化体的大小、数量和含量,才能最大限度地发挥过氧化体内代谢功能的多样性。除了转录调控外,人们对执行这一复杂节日的机制知之甚少。在这里,我们使用补充的高含量筛子来跟踪大多数酵母,酿酒酵母,蛋白质在油酸生长过程中的变化。我们发现了细胞结构的广泛变化,并鉴定了几种与过氧体共定位的蛋白质,这些蛋白质以前没有被认为是过氧酶体蛋白。Ymr018w是新近发现的一种功能未知的蛋白质,类似于酵母和人的过氧化体靶向受体Pex5。我们证明了Ymr018w是一种新的过氧体靶向受体,它以一组基质蛋白为靶向过氧酶体。因此,我们将其重命名为Ymr018w,Pex9,并认为Pex9是一种条件特异性靶向受体,能够根据代谢需要动态重新连接过氧化物体。此外,我们认为在脊椎动物中也可能存在Pex5样受体。
To optimally perform the diversity of metabolic functions that occur within peroxisomes, cells must dynamically regulate peroxisome size, number and content in response to cell state and the environment. Except for transcriptional regulation little is known about the mechanisms used to perform this complicated fete. Here we used complementary high content screens to follow changes in most of the yeast, Saccharomyces cerevisiae, proteins during growth in oleate. We found extensive changes in cellular architecture and identified several proteins co-localizing with peroxisomes that have not previously been considered peroxisomal proteins. One of the newly identified peroxisomal proteins, Ymr018w, is a protein with an unknown function that is similar to the yeast and human peroxisomal targeting receptor Pex5. We demonstrate that Ymr018w is a novel peroxisomal targeting receptor that targets a subset of matrix proteins to peroxisomes. We have therefore renamed Ymr018w, Pex9, and suggest that Pex9 is a condition-specific targeting receptor that enables the dynamic rewiring of peroxisomes in response to metabolic needs. Moreover, we suggest that Pex5-like receptors may also exist in vertebrates.
