In vivo Imaging of oskar mRNA transport reveals the mechanism of posterior localization [PDF]

, 2008
oskar mRNA localization to the posterior of the Drosophila oocyte defines where the abdomen and germ cells form in the embryo. Although this localization requires microtubules and the plus end-directed motor, kinesin, its mechanism is controversial and ...

HTLV-1 Tax plugs and freezes UPF1 helicase leading to nonsense-mediated mRNA decay inhibition

Nature Communications, 2018
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 ...

A Homozygous Frameshift Variant in KHDC4 Is Associated With a Syndromic Inherited Retinal Disease in Humans

Clinical Genetics, EarlyView.
We identified a homozygous frameshift variant in KHDC4 (c.1535_1538del: (p.Lys512Argfs*8) in a consanguineous family with syndromic Retinitis Pigmentosa. Functional characterization shows aberrant protein mislocalisation from nuclear speckles to a diffuse pattern.

Investigation of the role of PNRC2 in nonsense-mediated mRNA decay in human cells

, 2016
Nonsense-mediated mRNA decay (NMD) is best known as a eukaryotic surveillance mechanism that targets mRNAs containing premature termination codons (PTCs) for degradation.

Antisense oligonucleotide-directed inhibition of nonsense-mediated mRNA decay

, 2016
Nonsense-mediated mRNA decay (NMD) is a cellular quality-control mechanism that is thought to exacerbate the phenotype of certain pathogenic nonsense mutations by preventing the expression of semi-functional proteins. NMD also limits the efficacy of read-

A novel deep intronic EIF2AK3 variant disrupts splicing and causes Wolcott–Rallison syndrome

Diabetic Medicine, EarlyView.
Abstract Aim Deep intronic variants can disrupt splicing and cause monogenic disease but are missed by routine genetic testing. This study assessed the contribution of deep intronic variants to Wolcott–Rallison syndrome (WRS), a recessive disorder characterized by early‐onset diabetes and progressive multisystem disease caused by loss‐of‐function ...

GIGYF2: A Multifunctional Regulator at the Crossroads of Gene Expression, mRNA Surveillance, and Human Disease

Cells
GIGYF2 (Grb10-interacting GYF protein 2) functions as a versatile adaptor protein that regulates gene expression at various levels. At the transcriptional level, GIGYF2 facilitates VCP/p97-mediated extraction of ubiquitylated Rpb1 from stalled RNA ...

Coordinated regulation of PIEZO2 by alternative splicing, post‐translational modification, membrane trafficking and protein partners

The Journal of Physiology, EarlyView.
Abstract figure legend Regulatory mechanisms such as alternative splicing, post‐translational modification, membrane trafficking, and protein interactions control channel gating, membrane abundance, and overall activity of PIEZO2. Proper regulation supports PIEZO2‐dependent proprioceptive, somatosensory, nociceptive, pruriceptive and interoceptive ...

Trying to make sense in nonsense-mediated mRNA decay

, 2014
Despite over 30 years of research, the molecular mechanisms of nonsense-mediated mRNA decay (NMD) are still not well understood. NMD appears to exist in most eukaryotes and is intensively studied in S. cerevisiae, C. elegans, D.

Biallelic Truncating Variant in LRGUK Is Associated With Severe Multiple Morphological Abnormalities of the Sperm Flagella and Sperm Nuclear Defects in Humans

Clinical Genetics, Volume 110, Issue 5, Page 538-548, November 2026.
A homozygous truncating variant in LRGUK results in loss of the LRGUK protein and causes multiple morphological abnormalities of the flagella (MMAF), disrupted axonemal architecture, central pair defects, abnormal chromatin organization, and severe male infertility, establishing LRGUK as a novel human infertility gene.
