Probable ATP-binding RNA helicase which plays a central role during spermatogenesis by repressing transposable elements and preventingTheir mobilization, which is essential forThe germline integrity. Acts viaThe piRNA metabolic process, which mediatesThe repression of transposable elements during meiosis by forming complexes composed of piRNAs and Piwi proteins and governThe methylation and subsequent repression of transposons. Its association with PIWIL4 andThe piP-bodies suggests a participation inThe secondary piRNAs metabolic process.
