DND1-NANOS3 shapes the PGC transcriptome via a heptanucleotide sequence in mRNA 3' UTRs.
Primordial germ-cell survival requires joint function of the RNA-binding proteins (RBPs) DND1 and NANOS3, yet how they collaborate has not been established. Here, we discover a paradigm of "two-factor authorization," where RBPs with low (DND1) or no (NANOS3) sequence specificity jointly repress RNAs via a unique high-i...
