Identification of the components of PRDM14 complex in ESCs


ABSTRACT: We investigated the N-terminal domain of PRDM14, which has no discernable functional domain, and its contribution to the maintenance of pluripotency. We performed a mass spectrometry analysis of the PRDM14-containing complex to disclose partner molecules that bind to the N-terminal domain of PRDM14.

The pluripotency-associated transcriptional network is regulated by a core circuitry of transcription factors. The PR domain-containing protein PRDM14 maintains pluripotency by activating and repressing transcription in a target gene-dependent manner. However, the mechanisms underlying dichotomic switching of PRDM14-mediated transcriptional control remain elusive. Here, we identified C-terminal binding protein 1 and 2 (CtBP1 and CtBP2; generically referred to as CtBP1/2) as components of the PRD  ...[more]
