BAHCC1 binds H4K20me1 to facilitate the MCM complex loading and DNA replicationNature communications · 2025
Summary (written by the submitters)
Methylation of histone H4 lysine 20 (H4K20), such as H4K20 mono-methylation (H4K20me1), regulates the biological processes of DNA replication, cell cycle progression, and DNA damage repair. Whereas H4K20me1 is knowingly written by SET8 (also known as PR-Set7) and erased by PHF8 (also known as KDM7B), the mechanism underlying H4K20me1-mediated regulation of DNA replication remains murky.

Here, we report that a conserved tandem Tudor domain of BAHCC1 (BAHCC1TTD) specifically reads H4K20me1. Our biochemical, structural and cellular analyses demonstrated that the recognition of H4K20me1 by BAHCC1TTD facilitates the BAHCC1 recruitment onto the replication origins, where BAHCC1 interacts and recruits components of Minichromosome Maintenance (MCM) complex, a critical partner machinery of Origin Replication Complex (ORC) for mediating DNA replication. Combined actions of the H4K20me1-reading BAHCC1 and the H4K20me2-reading ORC ensure optimal genomic loading of MCM proteins. Depletion of BAHCC1, or disruption of BAHCC1TTD:H4K20me1 interaction, affected H4K20me1 homeostasis and MCM complex loading, leading to impaired DNA replication and defective cell cycle progression. Together, this study identifies a conserved BAHCC1TTD as an effector linking H4K20me1 to MCM recruitment for efficient DNA replication.

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.

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE213114_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.

Raw reads on ENA ↗

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.
