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.

New preprint! We solve a mystery you didn't know existed. Mitotic cells lack new transcription but require ongoing translation. Interphase mRNA half life is only 2-4 hrs. So how do cells arrest in mitosis for hours without depleting their transcriptomes?

Global inhibition of deadenylation stabilizes the transcriptome in mitotic cells
