DESCRIPTION

Also known as PO5F1_HUMAN, POU5F1, OCT3, OCT4, OTF3. Transcription factor that binds to the octamer motif (5'-ATTTGCAT-3'). Forms a trimeric complex with SOX2 or SOX15 on DNA and controls the expression of a number of genes involved in embryonic development such as YES1, FGF4, UTF1 and ZFP206. Critical for early embryogenesis and for embryonic stem cell pluripotency. Interacts with PKM. Interacts with WWP2. Interacts with UBE2I and ZSCAN10 (By similarity). Interacts with PCGF1 (PubMed:26687479). Interacts with ESRRB; recruits ESRRB near the POU5F1-SOX2 element in the NANOG proximal promoter; the interaction is DNA independent (By similarity). Interacts with ZNF322 (By similarity). Interacts with MAPK8 and MAPK9; the interaction allows MAPK8 and MAPK9 to phosphorylate POU5F1 on Ser-355 (By similarity). Interacts (when phosphorylated on Ser-355) with FBXW8 (By similarity). Interacts with FBXW4 (By similarity). Interacts with SOX2 and SOX15; binds synergistically with either SOX2 or SOX15 to DNA (By similarity).
