Global profiling of regulatory elements in the histone benzoylation pathway.

Lysine benzoylation (Kbz) is a recently discovered post-translational modification associated with active transcription. However, the proteins for maintaining and interpreting Kbz and the physiological roles of Kbz remain elusive. Here, we systematically characterize writer, eraser, and reader proteins of histone Kbz in S.

Taf14 recognizes a common motif in transcriptional machineries and facilitates their clustering by phase separation.

Saccharomyces cerevisiae TBP associated factor 14 (Taf14) is a well-studied transcriptional regulator that controls diverse physiological processes and that physically interacts with at least seven nuclear complexes in yeast. Despite multiple previous Taf14 structural studies, the nature of its disparate transcriptional regulatory functions remains opaque. Here, we demonstrate that the extra-terminal (ET) domain of Taf14 (Taf14) recognizes a common motif in multiple transcriptional coactivator proteins from several nuclear complexes, including RSC, SWI/SNF, INO80, NuA3, TFIID, and TFIIF.

The Structural Basis for Specific Recognition of H3K14 Acetylation by Sth1 in the RSC Chromatin Remodeling Complex.

The Saccharomyces cerevisiae RSC (Remodel the Structure of Chromatin) complex is a chromatin-remodeling complex and plays essential roles in transcription regulation and DNA repair. The acetylation of H3 Lysine14 (H3K14Ac) enhances the RSC retention on nucleosomes and increases the remodeling activity of RSC. However, which RSC component recognizes H3K14Ac remains unclear.
