SOX2 is not only a pioneer transcription factor with critical roles in stem cell function and cell reprogramming but also a potent oncogene for a multitude of squamous cancers. How SOX2 exerts a potent oncogenic activity in squamous lineage is largely unknown. Here we uncovered SOX2 a p...
Multiple myeloma (MM) remains an incurable hematologic malignancy despite advances in treatment. While obesity is a well-established risk factor, the underlying metabolic mechanisms by which adipocytes contribute to disease progression remain elusive. Here, we uncover a critical m...
Increased protein acetylation is frequently observed in the failing heart, including in hearts with heart failure with preserved ejection fraction (HFpEF). However, the role of protein acetylation in cardiac metabolic impairments during the pathogenesis of HFpEF remains insufficiently investigate...
Protein acetylation is a key recurring co- and posttranslational modification. How different types of acetylation respond to the same environmental stress is unknown. A member of the newly discovered family of plastid acetyltransferases (GNAT2), which is featuring both lysine- and N-terminal acetyl...
The identity and developmental potential of a human cell is specified by its epigenome that is largely defined by patterns of chromatin modifications including histone acetylation. Here we report high-resolution genome-wide mapping of diacetylation of histone H3 at Lys 9 and Lys 14 in resting and ac...
Fig. 2B: Semi-quantitative acetylation level on TULP3 in the presence of either empty pcDNA 3.1(+), Myc-p300, FLAG-PCAF or FLAG-GCN5 following immunoprecipitation.
Protein post-translational modifications transmit signals in part by creating binding sites for effector molecules. This is especially true in epigenetic pathways where histone tails are heavily modified, resulting in the recruitment of molecules that can affect transcription. One such molecule, pla...
The recognition of modified histones by “reader” proteins constitutes a key mechanism regulating gene expression in the chromatin context. Compared with the great variety of readers for histone methylation, few protein modules that recognize histone acetylation are known. Here we show that the evolu...
