Evolutionary analysis of the #nuclease Artemis suggests an important role in the domestication of RAG-like #transposons, such as that which gave rise to V(D)J recombination. Conserved residues crucial for nuclease activity are also identified @PLOSBiology https://plos.io/3RuyNpl

Tiere kontrollieren die Ausbreitung von #Transposons im #Genom sehr streng. Wie @s_falk et al. von den @maxperutzlabs verkünden, helfen dabei kurze #RNA's, an deren Herstellung ein neuartiger #Enzym-Typ mitwirkt. — Larissa Tetsch erzählt uns mehr darüber: https://www.laborjournal.de/editorials/2905.php
