Rapidly evolving protointrons in Saccharomyces genomes revealed by a hungry spliceosome. [PDF]

, 2019
Introns are a prevalent feature of eukaryotic genomes, yet their origins and contributions to genome function and evolution remain mysterious. In budding yeast, repression of the highly transcribed intron-containing ribosomal protein genes (RPGs ...

Neurodevelopmental Disorder with Dystonia and Chorea Linked to De Novo Variants in the Splicing Regulator SRRM4

Movement Disorders, EarlyView.
Abstract Background SRRM4 is an exclusively neural‐expressed splicing‐factor gene not yet associated with a monogenic condition. Objective We sought to delineate movement disorders caused by SRRM4 variants. De novo splice‐donor‐site variants at position +2 of intron 5 of SRRM4 (c.464+2T>C, c.464+2T>A) occurred in three unrelated patients with dystonia ...

Resistance of mRNAs with AUG-proximal nonsense mutations to nonsense-mediated decay reflects variables of mRNA structure and translational activity. [PDF]

, 2015
Acessível em: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4513866/Nonsense-mediated mRNA decay (NMD) is a surveillance pathway that recognizes and selectively degrades mRNAs carrying premature termination codons (PTCs).

Jervell and Lange‐Nielsen Syndrome Related Clinical Genetics and Experimental Models

Pediatric Discovery, EarlyView.
ABSTRACT Jervell and Lange‐Nielsen syndrome (JLNS) is defined by electrocardiographic QT prolongation and sensorineural hearing loss, caused by homozygous or compound heterozygous variants in KCNQ1 and/or KCNE1. KCNQ1 encodes the alpha subunit Kv7.1 of the ion channels accountable for slow delayed rectifier potassium currents (IKs), whereas KCNE1 ...

A c.726C>G (p.Tyr242Ter) nonsense mutation-associated with splicing alteration (NASA) of WDR45 gene underlies β-propeller protein-associated neurodegeneration (BPAN)

Heliyon
Neurodegeneration with brain iron accumulation (NBIA) is a clinically and genetically heterogeneous disease characterized by increased iron deposition in the basal ganglia and progressive degeneration of the nervous system in adulthood. However, in early

Position of Premature Termination Codons Determines Susceptibility of hERG Mutations to Nonsense-Mediated mRNA Decay in Long QT Syndrome

, 2014
The degradation of human ether-a-go-go-related gene (hERG, KCNH2) transcripts containing premature termination codon (PTC)mutations by nonsense-mediatedmRNA decay (NMD) is an importantmechanismof long QT syndrome type 2 (LQT2).

Relationship Between PTBP1 and Pancreatic Cancer Based on microRNA and Behavior During TYMS‐Mediated Carcinogenesis

Cancer Science, EarlyView.
Corresponding Author and colleagues identify a pancreas‐enriched microRNA, miR‐216b‐5p, that suppresses PTBP1 and its downstream effector TYMS. Their findings reveal a novel miR‐216b‐5p/PTBP1/TYMS regulatory axis driving pancreatic cancer progression and establish PTBP1 as a central molecular regulator of tumor biology beyond its metabolic role ...

Genome-wide profiling of uncapped mRNA [PDF]

, 2012
Gene transcripts are under extensive posttranscriptional regulation, including the regulation of their stability. A major route for mRNA degradation produces uncapped mRNAs, which can be generated by decapping enzymes, endonucleases, and small RNAs ...
