And yes, the people in the car are the authors: Sabrina Kückelmann, Sophie Theunissen, Volker Böhm @volkerboehm.bsky.social , and Niels Gehring.

I also used ChatGPT to generate an AI illustration of SMG8/SMG9 function. SMG8 and SMG9 function like driver-assistance systems: SMG1 can operate without them, but under challenging conditions, they help maintain control and efficiency.

Key findings: • SMG8/SMG9 loss → modest NMD defects • UPF1 phosphorylation only slightly increased • Complex integrity boosts efficiency, but is not strictly essential

We are excited to share our new paper in Nucleic Acids Research. Nonsense-mediated mRNA decay (NMD) is a surveillance pathway that detects and degrades faulty mRNAs. By probing the SMG1–SMG8–SMG9 complex, we show that NMD tolerates loss of key regulatory components better than expected.

🚨 Publication Alert 🚨 New work from our #CRC1678 members @volkerboehm.bsky.social and Niels Gehring in @narjournal.bsky.social shows that SMG8 and SMG9 act as nonessential but crucial modulators safeguarding the efficiency and resilience of the NMD pathway. academic.oup.com/nar/article/...

SMG1:SMG8:SMG9-complex integrity supports efficient execution of nonsense-mediated mRNA decay
Abstract. Nonsense-mediated mRNA decay (NMD) is a translation-dependent mRNA turnover pathway, which degrades transcripts containing premature termination

How are faulty #RNA degraded? New mechanistic insight into NMD: 1️⃣SMG5 & SMG6 PIN domains form a composite endonuclease (cPIN) 2️⃣ SMG5 completes the SMG6 active site, enabling efficient mRNA cleavage Fantastic collaboration with @labconti.bsky.social 🙏 👉 www.nature.com/articles/s41... 1/n

Composite SMG5-SMG6 PIN domain formation is essential for NMD - Nature Communications
Execution of mRNA cleavage in nonsense-mediated decay remained elusive. The authors show that SMG5 complements SMG6 to form a highly active, composite endonuclease with expanded catalytic center that ...

🔬🧬Fehlerhafte RNA erkennen und zerstören das macht der Nonsense-mediated mRNA Decay Forschende haben nun den zentralen Mechanismus des Kontrollsystems identifiziert. Die zwei Proteine – SMG5 und SMG6 – bilden gemeinsam eine molekulare „Schere“, die die fehlerhafte mRNA zerschneidet. uni.koeln/SVV5T
