A 7-bp insertion in the 3' untranslated region suggests the duplication and concerted evolution of the rabbit SRY gene

Genetics Selection Evolution, 2006
In this work we report the genetic polymorphism of a 7-bp insertion in the 3' untranslated region of the rabbit SRY gene. The polymorphic GAATTAA motif was found exclusively in one of the two divergent rabbit Y-chromosomal lineages, suggesting that its ...

The Phylogenetic Position of Vincetoxicum pannonicum (Borhidi) Holub Supports the Species' Allopolyploid Hybrid Origin

Acta Societatis Botanicorum Poloniae, 2020
The Pannonian endemic species Vincetoxicum pannonicum was described from specimens collected in Hungary and occurs at only few locations. It is considered “vulnerable” according to the International Red List.

DNA ligase LigE increases bacterial transformation with damaged extracellular DNA

FEBS Letters, EarlyView.
The DNA ligase LigE from the naturally competent Gram‐negative bacterium Neisseria gonorrhoaea increases transformation with cut extracellular DNA. This process is ATP‐dependent and relies on the catalytic activity of LigE; it also requires that LigE contains an intact periplasmic localisation sequence, indicating that ligE functions in the periplasm ...

Dissecting the Satellite DNA Landscape in Three Cactophilic Drosophila Sequenced Genomes

G3: Genes, Genomes, Genetics, 2017
Eukaryote genomes are replete with repetitive DNAs. This class includes tandemly repeated satellite DNAs (satDNA) which are among the most abundant, fast evolving (yet poorly studied) genomic components. Here, we used high-throughput sequencing data from

Soft motions encoded by the fold and mediated by conserved hinge sites drive V‐ATPase allosteric machinery and autoinhibition

FEBS Letters, EarlyView.
Vacuolar H+‐ATPase (V‐ATPase) is a multisubunit rotary proton pump that acidifies intracellular compartments. Using elastic network models, we identified conserved hinge residues that govern its large‐scale functional motions. We show that intrinsically encoded ‘soft modes’ drive critical functional transitions, including rotary catalysis and ...

SMORE: Synteny Modulator of Repetitive Elements

Life, 2017
Several families of multicopy genes, such as transfer ribonucleic acids (tRNAs) and ribosomal RNAs (rRNAs), are subject to concerted evolution, an effect that keeps sequences of paralogous genes effectively identical.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Inhibition of cyclin‐dependent kinases 12/13 using CT7439 as a treatment for colorectal cancer with CDK12 upregulation

Molecular Oncology, EarlyView.
The proposed mechanism of action for the CDK12/13 inhibitor and cyclin K degrader, CT7439. CDK12/13 inhibition interrupts transcription elongation, leading to increased DNA damage that results in cell death. This agent is a potentially novel treatment option for patients with colorectal cancer. Created in BioRender. Cyclin‐dependent kinase (CDK) 12 and

A Glimpse into the Satellite DNA Library in Characidae Fish (Teleostei, Characiformes)

Frontiers in Genetics, 2017
Satellite DNA (satDNA) is an abundant fraction of repetitive DNA in eukaryotic genomes and plays an important role in genome organization and evolution.

Concerted evolution within a trypsin gene cluster in Drosophila

Molecular Biology and Evolution, 1999
A cluster of four trypsin genes has previously been localized to cytological position 47D-F of the Drosophila melanogaster genome. One of these genes had been sequenced, and the presence of the other three genes was identified by cross-hybridization. Here, we present the DNA sequence of the entire genomic region encoding these four trypsin genes.
