PRDM14: a unique regulator for pluripotency and epigenetic reprogramming.

PRDM14 belongs to the PR domain-containing (PRDM) transcriptional regulators. Among the PRDM family members, PRDM14 shows specific expression in preimplantation embryos, primordial germ cells (PGCs), and embryonic stem cells (ESCs) in vitro, and accordingly plays a key role in the regulation of their pluripotency and epigenetic reprogramming, most notably, genome-wide DNA demethylation. The function of PRDM14 appears to be conserved between mice and humans, but it shows several characteristic differences between the two species. A precise understanding of the function of PRDM14 in mice and humans would shed new light on the regulation of pluripotency and the epigenome in these two species, providing a foundation for better control of stem cell fates in a broader context.
