How do cells sort which RNAs to keep or destroy? New preprint from THJ, Brenneke and Plaschka labs shows that export and decay machineries (TREX2/PAXT) both recognise UAP56-bound RNAs. Whether they’re exported or degraded depends on where in the nucleus this happens.

Eukaryotic genomes generate a plethora of polyadenylated (pA+) RNAs, that are packaged into ribonucleoprotein particles (RNPs). To ensure faithful gene expression, functional pA+ RNPs, including prote...

Thrilled to share our new Brockdorff lab paper at NSMB: we show that the primary role of m6A RNA modification on Xist is to promote RNA degradation. Xist turnover is mediated by the NEXT complex, not PAXT, and is independent of the m6A reader YTHDC1. www.nature.com/articles/s41...

Excited to share some new work from our group - www.biorxiv.org/content/10.1...

A great collaboration with @kurianlab.bsky.social that began with how an RBP (QKI) controls cardiomyocyte function, and led to uncovering a unique mechanism of direct interaction with U6 & the tri-snRNP at weak 5'SS

QKI ensures splicing fidelity during cardiogenesis by engaging the U6 tri-snRNP to activate splicing at weak 5ʹ splice sites

During organogenesis, precise pre-mRNA splicing is essential to assemble tissue architecture. Many developmentally essential exons bear weak 5'splice sites (5'SS) yet are spliced with high precision, ...

Many conserved exons in the heart and brain utilize weak 5 ′ splice sites, yet they are accurately spliced. But how? We show that splicing fidelity is actively enforced through a QKI-U6 checkpoint at the U1→U6 handover in essential cardiac genes during organogenesis.
