It took a while, but here we are. Our micDROP paper is out in @natcomms.nature.com, led by @atargt.bsky.social. She asked whether the sequence of a disordered region can self-recognize specifically. She measured this for ten IDRs in living yeast cells. www.nature.com/articles/s41...

The STA1–DOT2 interaction promotes nuclear speckle formation and splicing robustness in growth and heat stress responses
Abstract. Pre-mRNA splicing is carried out by the spliceosome, a large and dynamic ribonucleoprotein complex. The spliceosome is known to be stored in nucl

Excited to share our discovery of a new programmable RNA-guided DNA-targeting system hiding inside bacteriophages that predates CRISPR. We call it VIPR (Viral Interference Programmable Repeat), and it uses an entirely new logic to find its targets. Thread + link below.
