Our analyses also support a model by which new invading ERVs that landed at young KZFP gene clusters likely promoted the expansion and diversification of the KZFP gene repertoire in mice, by facilitating non-allelic homologous recombination events and large segmental duplications

By combining multiple long-read sequencing technologies, we achieved a first detailed comparative analysis of young KZFP gene clusters in the mouse lineage, revealing a previously underestimated heterogeneity of these loci between mouse strains and species
