在拟南芥中，BTB/POZ-MATH（BPM）蛋白包括六个成员的小家族。它们以前被描述为使用它们的广泛复合物、电车轨道、bric-a-brac/POX病毒和锌。指（BTB/POZ）结构域与CUL 3a和CUL 3b组装，并潜在地用作植物中基于cullin的E3连接酶的底物衔接子。在这篇文章中，我们表明，BPM也可以组装的乙烯反应因子/Apetala 2转录因子家族的成员，这是介导的meprin和TRAF（肿瘤坏死因子受体相关因子）同源（MATH）域。此外，我们提供了一个详细的描述BPM基因在不同组织中的表达模式和非生物胁迫处理，以及它们的亚细胞定位。这项工作连接，为。首次发现BPM蛋白具有乙烯反应因子/Apetala 2家族成员，这可能代表了一种新的转录调控机制。
In Arabidopsis thaliana, the BTB/POZ-MATH (BPM) proteins comprise a small family of six members. They have been described previously to use their broad complex, tram track, bric-a-brac/POX virus and zinc. finger (BTB/POZ) domain to assemble with CUL3a and CUL3b and potentially to serve as substrate adaptors to cullin-based E3-ligases in plants. In this article, we show that BPMs can also assemble with members of the ethylene response factor/Apetala2 transcription factor family, and that this is mediated by their meprin and TRAF ( tumor necrosis factor receptor-associated factor) homology (MATH) domain. In addition, we provide a detailed description of BPM gene expression patterns in different tissues and on abiotic stress treatments, as well as their subcellular localization. This work connects, for the. first time, BPM proteins with ethylene response factor/Apetala2 family members, which is likely to represent a novel regulatory mechanism of transcriptional control.
