De novo prediction of PTBP1 binding and splicing targets reveals unexpected features of its RNA recognition and function. [PDF]

open access: yes, 2014
The splicing regulator Polypyrimidine Tract Binding Protein (PTBP1) has four RNA binding domains that each binds a short pyrimidine element, allowing recognition of diverse pyrimidine-rich sequences.

Advances and Strategies in Enhancing mRNA Cancer Vaccines

open access: yesAdvanced Materials, EarlyView.
Messenger RNA (mRNA) vaccines offer a powerful approach for cancer immunotherapy, but their clinical impact remains limited by delivery challenges and suboptimal immune activation. This review discusses key biological barriers and design strategies—including structural optimization, immunomodulation, organ targeting delivery, and advanced nanocarriers ...

Circularly permuted tRNA genes: their expression and implications for their physiological relevance and development.

open access: yesFrontiers in Genetics, 2014
A number of genome analyses and searches using programs that focus on the RNA-specific bulge-helix-bulge (BHB) motif have uncovered a wide variety of disrupted tRNA genes.

Mutation of Arabidopsis SPLICEOSOMAL TIMEKEEPER LOCUS1 Causes Circadian Clock Defects [PDF]

open access: yes, 2012
The circadian clock plays a crucial role in coordinating plant metabolic and physiological functions with predictable environmental variables, such as dusk and dawn, while also modulating responses to biotic and abiotic challenges.

Cryptic Splicing of GAP43 mRNA is a Novel Hallmark of TDP‐43‐Associated ALS and AD

open access: yesAdvanced Science, EarlyView.
TDP‐43 dysfunction disrupts RNA processing, inducing cryptic exon 4a1 inclusion in GAP43 and reducing its protein levels. This aberrant splicing impairs axonal regeneration and contributes to neurodegeneration in ALS and AD. RNA‐seq of patient brains reveals GAP43 downregulation and 4a1 upregulation, identifying cryptic exon 4a1 as a potential ...

Widespread Separation of the Polypyrimidine Tract From 3′ AG by G Tracts in Association With Alternative Exons in Metazoa and Plants

open access: yesFrontiers in Genetics, 2019
At the end of introns, the polypyrimidine tract (Py) is often close to the 3′ AG in a consensus (Y)20NCAGgt in humans. Interestingly, we have found that they could also be separated by purine-rich elements including G tracts in thousands of human genes ...

Exons, introns and DNA thermodynamics

open access: yes, 2005
The genes of eukaryotes are characterized by protein coding fragments, the exons, interrupted by introns, i.e. stretches of DNA which do not carry any useful information for the protein synthesis.

Group II intron splicing factors in plant mitochondria

open access: yesFrontiers in Plant Science, 2014
Group II introns are large catalytic RNAs (ribozymes) which are found in bacteria and organellar genomes of several lower eukaryotes, but are particularly prevalent within the mitochondrial genomes (mtDNA) in plants, where they reside in numerous ...

IncRNA‐ZFAS1, an Emerging Gate‐Keeper in DNA Damage‐Dependent Transcriptional Regulation

open access: yesAdvanced Science, EarlyView.
LncZFAS1 plays a crucial role during DNA damage response in mammalian cells. Loss of lncZFAS1 results in deficient DNA lesion removal and reduced cell viability. Mechanistically, lncZFAS1 modulates RNAPII phosphorylation and transcription and thereby promotes both GG‐NER and TC‐NER upon UV damage.

Large introns in relation to alternative splicing and gene evolution: a case study of Drosophila bruno-3 [PDF]

open access: yes, 2009
Background: Alternative splicing (AS) of maturing mRNA can generate structurally and functionally distinct transcripts from the same gene. Recent bioinformatic analyses of available genome databases inferred a positive correlation between intron length ...
