Genetic, structural, and biochemical analyses of IS607-family transposons shows that the DNA translocation reaction proceeds very differently from other reactions promoted by serine recombinases.
Transposon activation during male gametogenesis is caused by interactions between DNA demethylation and linker histone H1, developmental depletion of which promotes pollen fertility.
Building on previous work (Plumb et al., 2015), it is shown that the Sec61 translocon controls the oligomerization, activation and inactivation of Ire1α during endoplasmic reticulum stress.
A DNA transposon, or ‘jumping gene’, controls its amplification within a genome through a competition between the enzyme multimers that are responsible for its mobility.
Structural and biochemical analyses of a eukaryotic DNA transpososome in the integration step reveal how mariner/Tc1 transposons are selectively integrated into a TA target sequence.
Hydrogen-deuterium exchange mass spectrometry reveals nucleotide-driven conformational regulation of Sec protein-channel to help impose directionality for protein transport through the Sec complex.
Hundreds of retrovirus-like sequences have features that suggest they might be gene enhancers, but only a small fraction displays gene-regulating activity in experiments on mouse stem cells.
