ADR-2 regulates fertility and oocyte fate in Caenorhabditis elegans.

ABSTRACT: RNA-binding proteins (RBPs) play essential roles in coordinating germline gene expression and development in all organisms. Here, we report that loss of ADR-2, a member of the adenosine deaminase acting on RNA family of RBPs and the sole adenosine-to-inosine RNA-editing enzyme in Caenorhabditis elegans, can improve fertility in multiple genetic backgrounds. First, we show that loss of RNA editing by ADR-2 restores normal embryo production to subfertile animals that transgenically express a vitellogenin (yolk protein) fusion to green fluorescent protein. Using this phenotype, a high-throughput screen was designed to identify RBPs that when depleted yield synthetic phenotypes with loss of adr-2. The screen uncovered a genetic interaction between ADR-2 and SQD-1, a member of the heterogeneous
