Here, we presented an integrative database named DrLLPS (http://llps.biocuckoo.cn/) for proteins involved in liquid-liquid phase separation (LLPS), which is a ubiquitous and crucial mechanism for spatiotemporal organization of various biochemical reactions, by creating membraneless organelles (MLOs) in eukaryotic cells. From the literature, we manually collected 150 scaffold proteins that are drivers of LLPS, 987 regulators that contribute in modulating LLPS, and 8148 potential client proteins that might be dispensable for the formation of MLOs, which were then categorized into 40 biomolecular condensates. We searched potential orthologs of these known proteins, and in total DrLLPS contained 437 887 known and potential LLPS-associated proteins in 164 eukaryotes. Furthermore, we carefully annotated LLPS-associated proteins in eight model organisms, by using the knowledge integrated from 110 widely used resources that covered 16 aspects, including protein disordered regions, domain annotations, post-translational modifications (PTMs), genetic variations, cancer mutations, molecular interactions, disease-associated information, drug-target relations, physicochemical property, protein functional annotations, protein expressions/proteomics, protein 3D structures, subcellular localizations, mRNA expressions, DNA & RNA elements, and DNA methylations. We anticipate DrLLPS can serve as a helpful resource for further analysis of LLPS.
在这里,我们展示了一个名为 DrLLPS(http://llps.biocuckoo.cn/)的综合数据库,用于研究涉及液-液相分离(LLPS)的蛋白质。LLPS 是真核细胞中无膜细胞器(MLO)形成的一种普遍而关键的生化反应时空组织机制。我们从文献中手动收集了 150 种支架蛋白,这些蛋白是 LLPS 的驱动蛋白;987 种调节蛋白,有助于调节 LLPS;8148 种潜在的客户蛋白,这些蛋白可能对 MLO 的形成不是必需的,然后将它们分为 40 种生物分子凝聚物。我们搜索了这些已知蛋白的潜在同源物,总共 DrLLPS 包含了 164 种真核生物中 437887 种已知和潜在的与 LLPS 相关的蛋白。此外,我们通过使用来自 110 个广泛使用的资源的知识,仔细注释了八种模式生物中的与 LLPS 相关的蛋白,这些资源涵盖了 16 个方面,包括蛋白质无序区域、结构域注释、翻译后修饰(PTMs)、遗传变异、癌症突变、分子相互作用、疾病相关信息、药物靶点关系、理化性质、蛋白质功能注释、蛋白质表达/蛋白质组学、蛋白质 3D 结构、亚细胞定位、mRNA 表达、DNA 和 RNA 元件以及 DNA 甲基化。我们预计 DrLLPS 将成为进一步分析 LLPS 的有用资源。
