Although cohesin-sensitive, long-range enhancer activation is equivalent in nature to proximal activation. Cooperativity can arise from different levels of activation inputs operating on a non-linear response function. @eliasfriman.bsky.social @uoe-igc.bsky.social

Why can't we explain enhancer action despite 2 decades of chromosome conformation technologies? 😬
Our new study spearheaded by Leonid Mirny's group points to a flaw in our assumptions, and to a solution from physical principles

1/🧵 Can transcription factor condensate formation be explained without phase separation? Our new preprint introduces SPARK, a simulation tool that reproduces condensate behavior (clustering, fusion, FRAP) from diffusion & binding kinetics alone. Movie: 60 sec FRAP sim www.biorxiv.org/content/10.6...
