piRNAs

Piwi-interacting RNAs (piRNA) are a class small of RNA molecules that are expressed uniquely in mammalian spermatogenic cell lines. These are 26–31 nucleotides long and bigger that miRNAs and siRNAs. They are so named because of their capability of forming RNA-protein complexes with Piwi proteins. Piwi proteins are part of the family of Argonaute [...]
