  1. RAG Recombinase as a Selective Pressure for Genome Evolution

    Passagem-Santos, D.; Bonnet, M.; Sobral, D.; Trancoso, I.; Silva, J.G.; Barreto, V.M.; Athanasiadis, A.; Demengeot, J.; Pereira-Leal, J.B.
    The RAG recombinase is a domesticated transposable element co-opted in jawed vertebrates to drive the process of the so-called V(D)J recombination, which is the hallmark of the adaptive immune system to produce antigen receptors. RAG targets, namely, the Recombination Signal Sequences (RSS), are rather long and degenerated sequences, which highlights the ability of the recombinase to interact with a wide range of target sequences, including outside of antigen receptor loci. The recognition of such cryptic targets by the recombinase threatens genome integrity by promoting aberrant DNA recombination, as observed in lymphoid malignancies. Genomes evolution resulting from RAG acquisition is an...
