RNA-binding protein which binds to its own mRNA and target mRNAs to negatively regulate gene expression to modulate apoptosis and differentiation in the germline (PubMed:30728462). Negatively regulates the expression of the argonaute protein wago-4, and may thus play a role in RNA-mediated gene silencing (RNAi) in the germline (PubMed:30728462). {Experimental EvidencePubMed:30728462}.
