植物同源结构域(PHD)指已经成为能够识别或“阅读”翻译后组蛋白修饰和未修饰的组蛋白尾部的表观遗传效应物的最大家族之一。这些相互作用是高度特异性的,并且可以通过相邻的表观遗传标记和相邻的效应物来调节。最近发现一些PHD指也与非组蛋白蛋白相关。本文就PHD指靶向组蛋白和非组蛋白的分子机制和生物学效应作一综述。我们讨论了组蛋白修饰之间的串扰的意义和后果的组合读出选择性招聘的PHD手指含组分的染色质重塑和转录复合物。
Plant homeodomain (PHD) fingers have emerged as one of the largest families of epigenetic effectors capable of recognizing or ‘reading’ post-translational histone modifications and unmodified histone tails. These interactions are highly specific and can be modulated by the neighboring epigenetic marks and adjacent effectors. A few PHD fingers have recently been found to also associate with non-histone proteins. In this review, we detail the molecular mechanisms and biological outcomes of the histone and non-histone targeting by PHD fingers. We discuss the significance of crosstalk between the histone modifications and consequences of combinatorial readout for selective recruitment of the PHD finger-containing components of chromatin remodeling and transcriptional complexes.
