Piwi-interacting piRNAs are a major and essential class of small RNAs in the animal germ cells with a prominent role in transposon control. Efficient piRNA biogenesis and function require a cohort of proteins conserved throughout the animal kingdom. Here we studied Maelstrom (MAEL). which is essential for piRNA biogenesis and germ cell differentiation in flies and mice. https://www.pomyslnaszycie.com/
