ECLIP of Drosophila Asterix/Gtsf1 transfected in Drosophila ovarian somatic sheath (OSS) cells


ABSTRACT: Asterix/Gtsf1 has been previously been shown to be involved in the silencing of retrotransposons in animal germ cells through the piRNA pathway. Using eCLIP and a custom informatic pipeline, we found that Asterix/Gtsf1 binds directly to RNAs and preferentially interacts with tRNAs as a class. Given the role of tRNAs as primers for Long Terminal Repeat (LTR) transposons, this work implicates Asterix/Gtsf1 as exploiting tRNA dependence to identify transposon transcripts and promote piRNA silencing.
