RNA结合蛋白FUS介导生物分子凝聚物中的相分离,并通过与RNA聚合酶II聚类而在转录中起作用。FUS和RNA聚合酶II(CTD)的C-末端七肽重复序列形成的特定接触残基和相互作用模式已被提出,但没有直接探测。在这里,我们展示了RGG结构域如何有助于与FUS N末端低复杂性结构域(SYGQ LC)和RNA聚合酶II CTD的相分离。使用NMR光谱和分子模拟,我们证明了许多残基类型,而不仅仅是精氨酸-酪氨酸对,通过几种相互作用模式形成凝聚相接触,包括但不仅是sp2/π和阳离子-π相互作用。在还含有RNA聚合酶II CTD的相中,许多残基类型形成接触,包括由保守的人CTD赖氨酸形成的阳离子-π和氢键相互作用。因此,我们的数据表明,一个令人惊讶的广泛阵列的残基类型和模式解释FUS和RNA聚合酶II的共相分离。
The RNA-binding protein FUS mediates phase separation in biomolecular condensates and functions in transcription by clustering with RNA polymerase II. Specific contact residues and interactions modes formed by FUS and the C-terminal heptad repeats of RNA polymerase II (CTD) have been suggested but not probed directly. Here, we show how RGG domains contribute to phase separation with the FUS N-terminal low complexity domain (SYGQ LC) and RNA polymerase II CTD. Using NMR spectroscopy and molecular simulations, we demonstrate that many residue types, not solely arginine-tyrosine pairs, form condensed-phase contacts via several interaction modes including but not only sp2/π and cation-π interactions. In phases also containing RNA polymerase II CTD, many residue types form contacts, including both cation-π and hydrogen-bonding interactions formed by the conserved human CTD lysines. Hence, our data suggest a surprisingly broad array of residue types and modes explain co-phase separation of FUS and RNA polymerase II.
