Transcription factor that has both positive and negative roles on transcription. Required for the maintenance of embryonic stem cell identity and the reacquisition of pluripotency in somatic cells. May play an essential role in germ cell development at 2 levels: the reacquisition of potential pluripotency, including SOX2 up-regulation, and successful epigenetic reprogramming, characterized by EHMT1 repression. Its association with CBFA2T2 is required for the functions in pluripotency and germ cell formation (By similarity). Directly up- regulates the expression of pluripotency gene POU5F1 through its proximal enhancer. Binds to the DNA consensus sequence 5'-GGTC[TC]CTAA- 3'. {ECO:0000250|UniProtKB:E9Q3T6, ECO:0000269|PubMed:17942894, ECO:0000269|PubMed:20953172}. This is the function of PRDM14 (PR/SET domain 14, Ensembl gene identifier ENSG00000147596).
