  • Function

    Transcription 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 specificity

    Expressed 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 similarities

    Belongs to the POU transcription factor family. Class-5 subfamily.
    Contains 1 homeobox DNA-binding domain.
    Contains 1 POU-specific domain.

  • Developmental stage

    Highly expressed in undifferentiated embryonic stem cells and expression decreases gradually after embryoid body (EB) formation.

  • Domain

    The POU-specific domain mediates interaction with PKM2.

  • Post-translational
    modifications

    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 localization

    Nucleus. Expressed in a diffuse and slightly punctuate pattern.
