Glad to share our latest work that came out recently. We dive into the mechanisms of how Transcription Factors (TFs) like the nuclear receptor, ERα navigate the genome to find their targets.

Not that long ago, in vivo mouse enhancer design was a dream. Today, it's a reality! Using transfer deep learning to design de novo synthetic embryonic enhancers active in the heart, limb, and CNS. Great collab with

got super intrigued about EZHIP/CATACOMB, previously identified as a histone H3K27M mimic of PRC2. You can read about her efforts here:

Known for decades: DNA sequence drives nucleosome "rotational positioning" (which face of DNA contacts histones) But: How does this persist when remodelers & transcription constantly mobilize nucleosomes? Our new preprint 1/ :

Took us a bit, but proud of this published version. We now examine the genetic interaction of phosphorylation with oligomerization and where bulk and phospho-Swi6 localize. Wonder if chromatin affinity tuning to enable Suv39 H3K9me3 spreading is a conserved mechanism ?
