The new updates for Charles McAnany’s preprint “Positional Interpretation of Cis-Regulatory Code and Nucleosome Organization with Deep Learning Models” (www.biorxiv.org/content/10.1...) are up! We introduce PISA, a tool to visualize the cis-regulatory code. See a recap below:

The @zeitlingerlab.bsky.social is pleased to announce @sergio-gma91.bsky.social’s preprint “High-resolution binding data of TFIID and cofactors show promoter-specific differences in vivo” (www.biorxiv.org/content/10.6...). TLDR; TFIID behaves differently depending on promoter type. More below:

High-resolution binding data of TFIID and cofactors show promoter-specific differences in vivo
TFIID is instrumental in recognizing promoter sequences and initiating transcription, yet a cohesive understanding of how this complex interacts with and functions at different promoter types in vivo ...

Very proud of our new paper! Great job @mweilert.bsky.social, our experimentalists and modeling collaborator Rosa Martinez-Corral. It was fun to see the story grow and get feedback from various experts. Thank you all!

It’s been fun figuring out why some degenerate motifs matter while others don’t. Turns out there’s a whole syntax behind it, relying on cooperativity!

enhancer library is integrated into pooled long-range landing pad cells through Flpase-facilitated
recombination. After counterselection with Ganciclovir, cells with successful integration are enriched.
Cells are sorted into different bins based on mScarlet fluorescence level. Genomic DNA is extracted from
each bin; barcodes are amplified and sequenced. Reporter gene expression of each enhancer at each
distance is calculated as the weighted average of fluorescence levels across bins.

Our new preprint is out! Want to better visualize what your sequence-to-function profile learned? Here is PISA. It also comes in a new BPNet package, which can be used to train many genomics data sets, including MNase-seq data.

Very proud of two new preprints from the lab: 1) CREsted: to train sequence-to-function deep learning models on scATAC-seq atlases, and use them to decipher enhancer logic and design synthetic enhancers. This has been a wonderful lab-wide collaborative effort. www.biorxiv.org/content/10.1...
