Substitution of the α-lactalbumin transcription unit by a CAT cDNA within a BAC clone silenced the locus in transgenic mice without affecting the physically linked Cyclin T1 gene

open access: yesGenetics Selection Evolution, 2003
We recently reported that a goat bacterial artificial chromosome (BAC) clone conferred site-independent expression in transgenic mice of the two loci present within its insert, the ubiquitously expressed Cyclin T1 and the mammary specific β-lactalbumin ...

A conformational RNA zipper promotes intron ejection during non-conventional XBP1 mRNA splicing. [PDF]

open access: yes, 2015
The kinase/endonuclease IRE1 is the most conserved signal transducer of the unfolded protein response (UPR), an intracellular signaling network that monitors and regulates the protein folding capacity of the endoplasmic reticulum (ER).

Global Characterization of Fungal Mitogenomes: New Insights on Genomic Diversity and Dynamism of Coding Genes and Accessory Elements

open access: yesFrontiers in Microbiology, 2021
Fungi comprise a great diversity of species with distinct ecological functions and lifestyles. Similar to other eukaryotes, fungi rely on interactions with prokaryotes and one of the most important symbiotic events was the acquisition of mitochondria ...

In search of lost introns

open access: yes, 2007
Many fundamental questions concerning the emergence and subsequent evolution of eukaryotic exon-intron organization are still unsettled. Genome-scale comparative studies, which can shed light on crucial aspects of eukaryotic evolution, require adequate ...

Characterization of a disease-associated mutation affecting a putative splicing regulatory element in intron 6b of the cystic fibrosis transmembrane conductance regulator (CFTR) gene [PDF]

open access: yes, 2009
Cystic fibrosis (CF) is a common recessive disorder caused by >1600 mutations in the CF transmembrane conductance regulator (CFTR) gene. About 13% of CFTR mutations are classified as “splicing mutations,” but for almost 40% of these, their role in ...

Imaging Intron Evolution

open access: yesMethods and Protocols, 2022
Intron evolution may be readily imaged through the combined use of the “dot plot” function of the NCBI BLAST, aligning two sequences at a time, and the Vertebrate “Multiz” alignment and conservation tool of the UCSC Genome Browser. With the NCBI BLAST, an ideal alignment of two highly conserved sequences generates a diagonal straight line in the plot ...

Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Upregulation of Functional Kv11.1 Isoform Expression by Inhibition of Intronic Polyadenylation with Antisense Morpholino Oligonucleotides

open access: yes, 2014
The KCNH2 gene encodes the Kv11.1 potassium channel that conducts the rapidly activating delayed rectifier current in the heart. KCNH2 pre-mRNA undergoes alternative processing; intron 9 splicing leads to the formation of a functional, full-length Kv11 ...

Comparison of Lagostomus maximus amelogenin gene (AMELX) with other mammals [PDF]

open access: yes, 2016
The aim of this study was to compare the Lagostomus maximus AMEL sequence to assess their similarity with the AMEL genes from other mammals. Previously we reported a sequence of the AMEL gene of Lagostomus maximus which corresponds to the intron 3 of the
