Nuclear speckles are “hot”, but how do they actually sequester mRNPs? We find that stalled mRNPs are retained in nuclear speckles by a combinatorial RNA-binding protein network. www.biorxiv.org/content/10.6...

A combinatorial pre-mRNP retention factor network couples nuclear speckle architecture to splicing quality control
Cells must prevent incompletely spliced transcripts from entering the cytoplasm, yet how splicing status is recognized and converted into selective nuclear retention remains unclear. Here, we identify...

I am excited to announce that I will start the Brain Origins Lab at the Crick in March 2027! Using acoels as a model system, the lab will study how animal brains evolve, and how innovations in brain organisation enable new computational abilities and the evolution of complex behaviour.
