摘要

Transposon silencing within the germ line requires the proper processing of piRNA intermediates. However, the enzyme that is required for piRNA 3 end maturation in vertebrates remained enigmatic. Nishimura et al in this issue of EMBO Reports and two independent studies now identified PNLDC1 as the exonuclease that is responsible for piRNA 3 end processing and transposon silencing during mouse spermatogenesis. Together, these studies establish PNLDC1 as the piRNA 3 end trimmer in mouse.
