固有的无序蛋白质和区域及其相关的短线状基序在转录调控中起着关键作用。无序MYC相互作用基序(MIM)介导拟南芥MYC和MYB转录因子之间的相互作用,而MYC和MYB转录因子对硫代葡萄糖苷(GLS)合成至关重要。甘油三酯包括一类植物防御化合物,它们是由十字花目的祖先进化而来的。我们使用了一套不同的搜索策略来发现MIM在其他蛋白质和其他生物体中的其他出现,并通过结构预测、相互作用分析和生物物理实验来评估发现。我们的搜索揭示了许多MIM实例分布在被子植物谱系中。实验证实,几种新发现的含有MIM的蛋白质与MYC转录因子相互作用。只有在同一转录因子家族中发现的具有相似特征的HITS才能被验证,这表明结构预测和序列相似性是MIM存在是否介导相互作用的良好指标。实验验证的MIM在油菜目以外的生物中被发现,表明MIM的功能比调节GLS的生物合成更广泛。
Intrinsically disordered proteins and regions with their associated short linear motifs play key roles in transcriptional regulation. The disordered MYC-interaction motif (MIM) mediates interactions between MYC and MYB transcription factors in Arabidopsis thaliana that are critical for constitutive and induced glucosinolate (GLS) biosynthesis. GLSs comprise a class of plant defense compounds that evolved in the ancestor of the Brassicales order. We used a diverse set of search strategies to discover additional occurrences of the MIM in other proteins and in other organisms and evaluate the findings by means of structural predictions, interaction assays, and biophysical experiments. Our search revealed numerous MIM instances spread throughout the angiosperm lineage. Experiments verify that several of the newly discovered MIM-containing proteins interact with MYC TFs. Only hits found within the same transcription factor family and having similar characteristics could be validated, indicating that structural predictions and sequence similarity are good indicators of whether the presence of a MIM mediates interaction. The experimentally validated MIMs are found in organisms outside the Brassicales order, showing that MIM function is broader than regulating GLS biosynthesis.
