This is an incredible mechanistic dissection by the @kurianlab.bsky.social and Van Nostrand labs linking splicing choice to cardiac development!
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.

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, ...
