It was reported that another Pumilio, Pumilio2 (Pum2), exists in Xenopus oocytes and that this protein regulates the translation of RINGO mRNA, together with Deleted in Azoospermia-like protein (DAZL).

This system has been used to generate a transgenic line with stable and heritable knockdown of the gene Deleted in Azoospermia-like (Dazl), resulting in male sterility and germline transmission of the transgene through females.
When differentiation was induced, a subpopulation of these cells expressed markers such as Oct4, Growth differentiation factor 9b (GDF9b), the Deleted in Azoospermia-like (DAZL) gene and Vasa - all consistent with germ-cell formation.
