Summary (written by the submitters)
The mechanisms by which core clock components are spatially organized to ensure robust oscillations in mammals remains unclear. Here, we identify the positive limb factor BMAL1 as a phase-separating protein that forms dynamic biomolecular condensates essential for circadian transcription and behavior. Endogenous BMAL1 forms nuclear punctate that oscillate in sync with the circadian cycle.

Deletion analysis and optogenetic clustering identify an N_x001E_-terminal 90-amino acid intrinsically disordered region whose phosphorylation state tunes BMAL1 phase separation. Besides, BMAL1 condensates behave as multi-molecular assemblies that selectively recruit CLOCK, P300, MED1, and are specifically promoted by E-box DNA. Functionally, an IDR-deleted BMAL1 mutant fails to rescue rhythmic transcription in Bmal1-KO cells and cannot restore locomotor rhythms when reintroduced into the SCN specific Bmal1‑KO mice. These findings establish BMAL1 condensates as dynamic transcriptional hubs that couple phase separation to circadian rhythm in cells and in vivo.

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 GSE325862_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.

Also filed as BioProject PRJNA1442081 and SRA study SRP686268. Searching any of these in the dataset finder brings you back here.

Study design
36 samples, each with a distinct title — no replicated groups

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from 36 sample titles: 36 distinct titles with little repetition. These groups are guessed from the sample names, not taken from the paper, so check them against the sample list below before relying on them.
