KAT2A/2B acetylation of PLK4 prevents centrosome amplification
-
Results found that lack of GCN5 decreased the osteogenic differentiation of periodontal ligament stem cells (PDLSCs) and overexpression of GCN5 rescued osteogenic deficiency in PDLSCs from periodontitis patients. Mechanistically, GCN5 regulated DKK1 expression by acetylation of Histone H3 lysine 9 (H3K9) and Histone H3 lysine 14 (H3K14) to regulate Wnt/beta catenin pathway of PDLSCs.
-
findings reveal an important mechanism of histone modification and demonstrate that local generation of succinyl-CoA by the nuclear alpha-KGDH complex coupled with the succinyltransferase activity of KAT2A is instrumental in histone succinylation, tumour cell proliferation, and tumour development
-
GCN5 upregulation is especially common in UCCs. GCN5 knockdown impeded growth of specific UCCs, whereas PCAF knockdown elicited minor effects.
-
Our results suggest that GCN5 is present at telomeres and opposes telomere recombination, in contrast to PCAF that may indirectly favour them in ALT cells.
-
This report documents a novel lncRNA, GClnc1, which may act as a scaffold to recruit the WDR5 and KAT2A complex and modify the transcription of target genes. This study reveals that GClnc1 is an oncogenic lncRNA in human gastric cancer.
-
To understand how Gcn5 discriminates between different acyl-CoA molecules, structures of the catalytic domain of human Gcn5L2 bound to propionyl-CoA and butyryl-CoA were determined.
-
Data suggest that expression of GCN5 (histone acetyltransferase GCN5) is induced in skeletal muscle during a 48-hour fast; in contrast, expression of SIRT1 (sirtuin 1) remains unchanged.
-
Orc5 associates with the H3 histone acetyl transferase GCN5 (also known as KAT2A), and this association enhances the chromatin-opening function of Orc5.
-
Methionine was the only essential amino acid that rapidly induced PGC-1alpha acetylation through activating the GCN5 acetyltransferase.
-
these results may point to the GCN5-NF-kappaB pathway as a novel potential molecular target for stem cell mediated regenerative medicine and the treatment of metabolic bone diseases such as osteoporosis.
-
Acetyltransferase p300 collaborates with chromodomain helicase DNA-binding protein 4 (CHD4) to facilitate DNA double-strand break repair
-
Suggest lysine acetyltransfer as a potential regulator of platelet actin dynamics, and potential roles for lysine acetylation in the molecular coordination of platelet activation and function.
-
Data uncover GCN5 as a negative regulator of C/EBPalpha and demonstrate the importance of C/EBPalpha acetylation in myeloid differentiation.
-
GCN5 Potentiates Glioma Proliferation and Invasion via STAT3 and AKT Signaling Pathways
-
results thus demonstrate that the catalytic activity of GCN5 is stimulated by subunits of the ADA2a- or ADA2b-containing HAT modules and is further increased by incorporation of the distinct HAT modules in the ATAC or SAGA holo-complexes
-
GCN5 plays a positive role in human colon cancer development, and its suppression holds a great therapeutic potential in antitumor therapy
-
our results represent the first work demonstrating that GCN5 and PCAF exhibit different functions and antagonistically regulate the XBP-1S-mediated transcription.
-
Gcn5 and PCAF repress IFN-beta production in an enzymatic activity-independent and non-transcriptional manner: by inhibiting the innate immune signaling kinase TBK1 in the cytoplasm.
-
The antifibrotic effects of SIRT1 in systemic sclerosis were due in part to decreased expression and function of the acetyltransferase p300.
