The insertion of a mitochondrial selfish element into the nuclear genome and its consequences

open access: yesEcology and Evolution, 2020
Homing endonucleases (HE) are enzymes capable of cutting DNA at highly specific target sequences, the repair of the generated double‐strand break resulting in the insertion of the HE‐encoding gene (“homing” mechanism).

Systematic Identification and Functional Validation of New snoRNAs in Human Muscle Progenitors

open access: yesNon-Coding RNA, 2021
Small non-coding RNAs (sncRNAs) represent an important class of regulatory RNAs involved in the regulation of transcription, RNA splicing or translation.

Intron Mobility: Invasive introns [PDF]

open access: yesCurrent Biology, 1994
The evidence that introns in fungal and plant organellar DNAs are mobile genetic elements has strengthened significantly; like Shaw's cockney heroine, Eliza Doolittle, they cannot help but betray their origins.

High-yield production of multiple O-methylated phenylpropanoids by the engineered Escherichia coli–Streptomyces cocultivation system

open access: yesMicrobial Cell Factories, 2019
Background O-Methylated phenylpropanoids, which are generally present in small amounts in plants, have improved or distinct biological activities and pharmacological properties as opposed to their unmethylated counterparts.

RHD Genotypes in a Chinese Cohort of Pregnant Women

open access: yesFrontiers in Genetics, 2021
RHD variants in D¯ Chinese pregnant women arose difficulties in management during pregnancy. Therefore, this study aims to precisely manage D¯ pregnant women by evaluating the spectrum of RHD mutations in D¯ pregnant women and getting insight into the ...

Interplay of heavy chain introns influences efficient transcript splicing and affects product quality of recombinant biotherapeutic antibodies from CHO cells

open access: yesmAbs, 2023
Introns are included in genes encoding therapeutic proteins for their well-documented function of boosting expression. However, mis-splicing of introns in recombinant immunoglobulin (IgG) heavy chain (HC) transcripts can produce amino acid sequence ...

Proximity to the Promoter and Terminator Regions Regulates the Transcription Enhancement Potential of an Intron

open access: yesFrontiers in Molecular Biosciences, 2021
An evolutionarily conserved feature of introns is their ability to enhance expression of genes that harbor them. Introns have been shown to regulate gene expression at the transcription and post-transcription level.

An overview of RNA splicing and functioning of splicing factors in land plant chloroplasts

open access: yesRNA Biology, 2022
RNA splicing refers to a process by which introns of a pre-mRNA are excised and the exons at both ends are joined together. Chloroplast introns are inherently self-splicing ribozymes, but over time, they have lost self-splicing ability due to the ...

Intronization, de-intronization and intron sliding are rare in Cryptococcus [PDF]

open access: yesBMC Evolutionary Biology, 2009
Eukaryotic pre-mRNA gene transcripts are processed by the spliceosome to remove portions of the transcript, called spliceosomal introns. The spliceosome recognizes intron boundaries by the presence of sequence signals (motifs) contained in the actual transcript, thus sequence changes in the genome that affect existing splicing signals or create new ...
