Many molecular reactions in cells are tethered, often by #IDR. If 2 tethers are tied together (imagine handcuffed arms ⛓️‍💥), does this enhance or suppress their reactions? Formin, one of the major families of #cytoskeleton builders in eukaryotes, does exactly this.

Aster-based structures occur in cytoplasmic actin, the earl...

A remarkably simple question, "What is the likelihood landscape for the basic bursting transcription model?", reveals surprisingly complex underlying structure, with implications for the limits of what single-cell data can tell you.

We can make the flexibility of a model match the hypothesis being tested -- more flexibility is not always better, if it prohibits rejection of the hypothesis. Here is one simple case involving T cells where it made a difference! www.biorxiv.org/content/10.1...
