Genomes assembled from #metagenomes (a.k.a. MAGs) are awesome and have revolutionized our ability to study uncultivated microbes

...BUT: they still don't capture a lot of the 🦠 species that are out there

Very excited to announce that the single cell/nuc. RNA/ATAC/multi-ome resource from ENCODE4 is now officially public. This includes raw data, processed data, annotations and pseudobulk products. Covers many human & mouse tissues. 1/

Huge congrats to Anusri! This was quite a slog (for both of us) but we r very proud of this one! It is a long read but worth it IMHO. Methods r in the supp. materials. Bluetorial coming soon below 1/

(12/n) When we applied RCADEEM to the GHT-SELEX data, we saw that not some, but in fact most of the TFs from the C2H2-ZF family use alternative sets of their ZF domains to bind to different DNA molecules.

(6/n) Applying GHT-SELEX/MAGIX on 179 TFs, most of which were previously uncharacterized, we found that the majority do bind to the genome with high specificity, forming "peaks" that resemble those seen in vivo using ChIP-seq.

(1/n) What better way to start posting on Bluesky than to share our recent preprint, in collaboration with @timhughesto.bsky.social, on characterization of the intrinsic DNA binding specificities of 179 human transcription factors using a new assay, GHT-SELEX: www.biorxiv.org/content/10.1...
GHT-SELEX demonstrates unexpectedly high intrinsic sequence specificity and complex DNA binding of many human transcription factors
A long-standing challenge in human regulatory genomics is that transcription factor (TF) DNA-binding motifs are short and degenerate, while the genome is large. Motif scans therefore produce many fals...

An 18 month old boy presents to your office for a well child visit.

Parents have no concerns but do mention that he eats a lot of paper.

You astutely decide to check a CBC and iron studies but wonder why iron deficiency causes this strange symptom?

It always feels that bionformaticians are both a blessing and a curse when it comes to tool development. They come up with brilliant methods and implementations but tools lack all the support and robustness, often leading to giving up on the tools you love.

This post sums it up perfectly!
🧵 Bioinformatics faces a critical challenge: despite its importance, software quality often falls short due to the lack of proper development practices.

In our latest paper, we advocate for improving software quality in bioinformatics through teamwork.

Extensive binding of uncharacterized human transcription factors to genomic dark matter
Most of the human genome is thought to be non-functional, and includes large segments often referred to as "dark matter" DNA. The genome also encodes hundreds of putative and poorly characterized tran...
