The invention relate to the field of molecular biology and cell biology. It particularly relates to methods to direct integration of a nucleic acid of interest towards homologous recombination and uses thereof. The present invention discloses factors involved in integration of a nucleic acid by illegitimate recombination which provides a method to direct integration of a nucleic acid of interest to a pre-determined site, whereby said nucleic acid has homology at or around the said pre-determined site, in a eukaryote with a preference for non-homologous recombination comprising steering an integration pathway towards homologous recombination. Furthermore, the invention provides a method to direct integration of a nucleic acid of interest to a sub-telomeric and/or telomeric region in a eukaryote with a preference for non-homologous recombination.
