  • FunctionTranscription factor that binds to the octamer motif (5'-ATTTGCAT-3'). Forms a trimeric complex with SOX2 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.
  • Tissue specificityExpressed in developing brain. Highest levels found in specific cell layers of the cortex, the olfactory bulb, the hippocampus and the cerebellum. Low levels of expression in adult tissues.
  • Sequence similaritiesBelongs to the POU transcription factor family. Class-5 subfamily.
    Contains 1 homeobox DNA-binding domain.
    Contains 1 POU-specific domain.
  • Developmental stageHighly expressed in undifferentiated embryonic stem cells and expression decreases gradually after embryoid body (EB) formation.
  • DomainThe POU-specific domain mediates interaction with PKM2.
  • Post-translational
    Sumoylation enhances the protein stability, DNA binding and transactivation activity. Sumoylation is required for enhanced YES1 expression.
    Ubiquitinated; undergoes 'Lys-63'-linked polyubiquitination by WWP2 leading to proteasomal degradation.
  • Cellular localizationNucleus. Expressed in a diffuse and slightly punctuate pattern.
