Bacterial Enzyme Keeps Rotifers’ Transposable Elements in Check
Christie Wilcox, PhD | Mar 3, 2022 | 5 min read
Jumping genes in bdelloid rotifers are tamped down by DNA methylation performed by an enzyme pilfered from bacteria roughly 60 million years ago, a study finds.

Jumping Genes Put a Target on Cancerous Cells

Two studies find that tumor-specific antigens are often peptides that result from a splicing event between exons and transposable elements.
Transposable Elegance
Aileen Constans | Mar 5, 2000 | 2 min read
Transposons, mobile DNA elements found in the genomes of prokaryotic and eukaryotic organisms, move randomly from one site in a chromosome to another using a process catalyzed by transposases. This process, called transposition, occurs naturally but infrequently in cells as a means of genetic change. For many years scientists have used transposons for genetic research. A new system, combining Tn5 transposase and a Tn5-derived transposon to form a stable synaptic complex, forms the basis of EZ::
Schizophrenia’s Jumping Genetics
Jef Akst | Jan 6, 2014 | 2 min read
Researchers find evidence that transposable elements, also known as jumping genes, may contribute to the development of the psychiatric disorder.

Alu Leap May Explain Why Apes Don’t Have Tails
Annie Melchor | Sep 23, 2021 | 2 min read
A transposable element that jumped into the TBXT gene, which is linked to tail morphology, appears to be to blame for our missing appendage.
