Tdrd1 acts as a molecular scaffold for Piwi proteins and piRNA targets in zebrafish.


ABSTRACT: RNA libraries from immunoprecipitates of Tdrd1, Ziwi and Zili, total testis RNA, total RNA from 3 week old wild-type and tdrd1 mutant gonads. Both size selected and non-size selected libraries were made. Sequencing was performed using Illumina platform.

Piwi proteins function in an RNAi-like pathway that silences transposons. Piwi-associated RNAs, also known as piRNAs, act as a guide to identify Piwi targets. The tudor domain-containing protein Tdrd1 has been linked to this pathway but its function has thus far remained unclear. We show that zebrafish Tdrd1 is required for efficient Piwi-pathway activity and proper nuage formation. Furthermore, we find that Tdrd1 binds both zebrafish Piwi proteins, Ziwi and Zili, and reveals sequence specificit  ...[more]
