CC -!- FUNCTION: Transcription factor that binds to the octamer motif (5'-
CC ATTTGCAT-3'). Forms a trimeric complex with SOX2 or SOX15 on DNA and
CC controls the expression of a number of genes involved in embryonic
CC development such as YES1, FGF4, UTF1 and ZFP206. Critical for early
CC embryogenesis and for embryonic stem cell pluripotency.
CC {ECO:0000250|UniProtKB:Q01860, ECO:0000269|PubMed:19738434}.
CC -!- SUBUNIT: Interacts with PKM. Interacts with WWP2. Interacts with UBE2I
CC and ZSCAN10. Interacts with PCGF1. Interacts with ESRRB; recruits ESRRB
CC near the POU5F1-SOX2 element in the NANOG proximal promoter; the
CC interaction is DNA independent. Interacts with ZNF322. Interacts with
CC MAPK8 and MAPK9; the interaction allows MAPK8 and MAPK9 to
CC phosphorylate POU5F1 on Ser-355. Interacts (when phosphorylated on Ser-
CC 355) with FBXW8. Interacts with FBXW4. Interacts with SOX2 and SOX15;
CC binds synergistically with either SOX2 or SOX15 to DNA (By similarity).
CC {ECO:0000250|UniProtKB:P20263, ECO:0000250|UniProtKB:Q01860}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm. Nucleus. Note=Expressed in a diffuse
CC and slightly punctuate pattern. Colocalizes with MAPK8 and MAPK9 in the
CC nucleus. {ECO:0000250|UniProtKB:P20263, ECO:0000250|UniProtKB:Q01860}.
CC -!- DOMAIN: The POU-specific domain mediates interaction with PKM.
CC {ECO:0000250|UniProtKB:Q01860}.
CC -!- DOMAIN: The 9aaTAD motif is a transactivation domain present in a large
CC number of yeast and animal transcription factors.
CC {ECO:0000250|UniProtKB:Q01860}.
CC -!- PTM: Sumoylation enhances the protein stability, DNA binding and
CC transactivation activity. Sumoylation is required for enhanced YES1
CC expression (By similarity). {ECO:0000250|UniProtKB:P20263}.
CC -!- PTM: Ubiquitinated; undergoes 'Lys-63'-linked polyubiquitination by
CC WWP2 leading to proteasomal degradation.
CC {ECO:0000250|UniProtKB:P20263}.
CC -!- PTM: ERK1/2-mediated phosphorylation at Ser-111 promotes nuclear
CC exclusion and proteasomal degradation. Phosphorylation at Thr-235 and
CC Ser-236 decrease DNA-binding and alters ability to activate
CC transcription. {ECO:0000250|UniProtKB:Q01860}.
CC -!- BIOTECHNOLOGY: POU5F1/OCT4, SOX2, MYC/c-Myc and KLF4 are the four
CC Yamanaka factors. When combined, these factors are sufficient to
CC reprogram differentiated cells to an embryonic-like state designated
CC iPS (induced pluripotent stem) cells. iPS cells exhibit the morphology
CC and growth properties of ES cells and express ES cell marker genes.
CC {ECO:0000269|PubMed:19738434}.
CC -!- SIMILARITY: Belongs to the POU transcription factor family. Class-5
CC subfamily. {ECO:0000305}.
