Paper
SIRT2 antagonizes MOF function during mitotic entryScience advances · 2026
Summary (written by the submitters)
The control of G2/M transition is a key event for genome stability as it ensures proper completion of DNA replication and repair before progressing into mitosis. One of the key regulators of G2/M checkpoint is the H4K16Ac-acetyltransferase MOF, which plays a major role in chromatin structure, gene expression, DNA damage and genome stability.

Here we show that SIRT2, a member of the sirtuin family of NAD+-dependent deacetylases, antagonizes the role of MOF in G2/M. SIRT2 promotes specific inactivation of MOF through deacetylation and degradation of MOF, which results in re-expression of G2/M cell-cycle genes regulated by MOF. Underscoring the functional relevance of this antagonism, both factors play opposed roles in the deposition of the key mark H4K20me1 during G2/M. Consistently, loss of MOF in wt but not in SIRT2-/- cells induces a genome-wide deregulation of H4K20me1 distribution, which results in a premature loading of condensins. Our studies suggest that the G2/M checkpoint is shaped by the balance between both factors and involves condensing regulation and underscores the role of sirtuins in cell cycle control and genome stability under stress.

Download · which file do I need?

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE277367_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: Look for peak files (.bed, .narrowPeak) and signal tracks (.bigWig) among the supplementary files; the raw reads are on ENA.

Also filed as BioProject PRJNA1162051 and SRA study SRP533137. Searching any of these in the dataset finder brings you back here.
