We identify a female patient with a homozygous nonsense variant (p.Gln38Ter) in the LYSET gene. This is the first western report of a challenging case of an extensive diagnostic odyssey and demonstrates that the LYSET gene must be considered in the differential diagnosis when M6P‐labeled lysosomal enzymes are altered.

Protecting the proteome: Eukaryotic cotranslational quality control pathways. [PDF]
The correct decoding of messenger RNAs (mRNAs) into proteins is an essential cellular task. The translational process is monitored by several quality control (QC) mechanisms that recognize defective translation complexes in which ribosomes are stalled on

Biallelic SLC20A1 loss‐of‐function variant causes a previously unrecognized multisystem developmental disorder. We report the first homozygous case presenting with tetralogy of Fallot, renal agenesis, polydactyly, and growth impairment. Transcriptome analysis of patient‐derived fibroblasts suggests significant dysregulation of pathways critical for ...

UPF1-like helicase grip on nucleic acids dictates processivity
UPF1 is a highly processive helicase that plays an essential role in nonsense-mediated mRNA decay. Here the authors use single molecule binding assays to establish a functionally important relationship between helicase grip to nucleic acids, binding ...

Human NMD ensues independently of stable ribosome stalling
Nonsense-mediated mRNA decay (NMD) was thought to ensue when ribosomes fail to terminate translation properly. However, the authors observe similar ribosome occupancy at stop codons of NMD sensitive and insensitive mRNAs, showing that human NMD is not ...

The rice protein OsFKBP20‐1b protects key RNA‐surveillance factors from breakdown, so they can better eliminate defective messages. This RNA quality‐control boost reduces errors and helps plants survive drought, revealing a link between RNA control and drought tolerance.

Two optimized TadA‐derived base editors efficiently generate diverse splicing variants by targeting specific splice sites in potato. ABSTRACT Pre‐messenger RNA (pre‐mRNA) splicing is a critical mechanism for post‐transcriptional regulation in plants. Through alternative splicing, plants produce diverse transcriptomes and proteomes that finely regulate ...

HTLV-1 Tax plugs and freezes UPF1 helicase leading to nonsense-mediated mRNA decay inhibition
UPF1 is a central protein in nonsense-mediated mRNA decay (NMD), but contribution of its RNA processivity to NMD is unclear. Here, the authors show how the retroviral Tax protein interacts with and inhibits UPF1, and demonstrate that UPF1’s translocase ...

Nonsense‐mediated mRNA decay: novel mechanistic insights and biological impact
Nonsense‐mediated mRNA decay (NMD) was originally coined to define a quality control mechanism that targets mRNAs with truncated open reading frames due to the presence of a premature termination codon.
