(1/13) Excited to share the outcome of the IBIS Challenge! The IBIS challenge united dozens of teams across the world in tackling the problem of modeling transcription factor (TF) binding specificity using a diverse collection of experimental datasets for understudied human TFs.

Our paper on LARGE-scale benchmarking of motif discovery tools is published! nature.com/articles/s42...
It was a long, 7 years long journey, which coordinated efforts of 50+ researchers, proud to be on of them.
More results from Codebook about poorly studied TFs are coming soon.

(8/12) With that many PWMs at hand, we also demonstrate that several motifs can be easily combined into a better model with ArChIPelago: regression or Random Forest on top of PWM scans.

(7/12) Comparison of different tools yielded many surprises. On the one hand, underused motif discovery tools such as Dimont excel across different types of experimental data. On the other hand, no single tool or platform is enough to get the most for each TF and each data type.

(5/12) Testing all existing tools is hardly realistic. Focusing on position weight matrices (PWMs), we tested the most popular tools (e.g. MEME, HOMER), less popular yet powerful tools (e.g. ChIPMunk, Dimont), and a few advanced methods still able to yield PWMs (e.g. ExplaiNN, ProBound).

(3/12) There are a multitude of high-throughput methods for assessing the DNA binding specificity of transcription factors. The variety of existing motif discovery tools is even greater. Which one to use?

(2/12) The human genome encodes ~1.5 thousand transcription factors (TFs), and hundreds of them still lack "DNA motifs", i.e., compact human- and machine-readable representations of the TF-DNA binding specificity.

(6/7) 1,421 human TFs now have a characterized DNA-binding specificity, and nearly all 1,638 have been assayed. Analyses in doi.org/10.1101/2024... indicate, however, that many previously characterized TF binding specificities may be inaccurate.

(5/7) Collectively the uncharacterized TFs bind directly to tens of thousands of conserved sequences, providing biochemical functions for these sites. Intriguingly, many of these sites are in genomic “dark matter”. Explored further in doi.org/10.1101/2024...
