How does a mobile DNA sequence find its target ?

Researchers from the Laboratoire Pathologie et Virologie Moléculaire (CNRS/Inserm/Université Paris Diderot)2, in collaboration with researchers from CEA3 and a US laboratory4, have identified an interaction between two proteins that is essential for the integration of a transposable element into a specific area of the yeast genome. These results, published on 1 May 2015 in the journal Science, emphasize the role of these mobile DNA sequences in the evolution and adaptation of organisms, and their potential value for gene therapy.

1 A transposable element is a DNA sequence capable of moving independently in a genome. Such mobile sequences are present in all living organisms and are considered powerful drivers of evolution and biodiversity.
