== Function ==
[https://www.uniprot.org/uniprot/NANOG_MOUSE NANOG_MOUSE] Transcription regulator involved in inner cell mass and embryonic stem (ES) cells proliferation and self-renewal (PubMed:25825768). Imposes pluripotency on ES cells and prevents their differentiation towards extraembryonic endoderm and trophectoderm lineages. Blocks bone morphogenetic protein-induced mesoderm differentiation of ES cells by physically interacting with SMAD1 and interfering with the recruitment of coactivators to the active SMAD transcriptional complexes. Acts as a transcriptional activator or repressor. Binds optimally to the DNA consensus sequence 5'-TAAT[GT][GT]-3' or 5'-[CG][GA][CG]C[GC]ATTAN[GC]-3'. Binds to the POU5F1/OCT4 promoter (By similarity). Able to autorepress its expression in differentiating (ES) cells: binds to its own promoter following interaction with ZNF281/ZFP281, leading to recruitment of the NuRD complex and subsequent repression of expression. When overexpressed, promotes cells to enter into S phase and proliferation.[UniProtKB:Q9H9S0]<ref>PMID:12787504</ref> <ref>PMID:12787505</ref> <ref>PMID:14728807</ref> <ref>PMID:15502159</ref> <ref>PMID:16518401</ref> <ref>PMID:16791199</ref> <ref>PMID:16801560</ref> <ref>PMID:21915945</ref> <ref>PMID:22988117</ref> <ref>PMID:25825768</ref>
