Piwi-interacting RNAs are small regulatory RNAs with key roles in transposon silencing and regulation of gametogenesis. The production of mature piwi-interacting RNAs requires a critical step of trimming piwi-interacting RNA intermediates to achieve optimally sized piwi-interacting RNAs. The poly(A)-specific ribonuclease family deadenylase PNLDC1 is implicated in piwi-interacting RNA trimming in silkworms. The physiological function of PNLDC1 in mammals remains unknown. Using Pnldc1-deficient mice, here we show that PNLDC1 is required for piwi-interacting RNA biogenesis, transposon silencing, and spermatogenesis. Pnldc1 mutation in mice inhibits piwi-interacting RNA trimming and causes accumulation of untrimmed piwi-interacting RNA intermediates with 3′ end extension, leading to severe reduction of mature piwi-interacting RNAs in the testis. Pnldc1 mutant mice exhibit disrupted LINE1 retrotransposon silencing and defect in spermiogenesis. Together, these results define PNLDC1 as a mammalian piwi-interacting RNA biogenesis factor that protects the germline genome and ensures normal sperm production in mice. piRNAs are regulatory RNAs that play a critical role in transposon silencing and gametogenesis. Here, the authors provide evidence that mammalian PNLDC1 is a regulator of piRNA biogenesis, transposon silencing and spermatogenesis, protecting the germline genome in mice.
