ターゲット情報

  • 機能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.
  • 組織特異性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.
  • 配列類似性Belongs to the POU transcription factor family. Class-5 subfamily.
    Contains 1 homeobox DNA-binding domain.
    Contains 1 POU-specific domain.
  • 発生段階Highly expressed in undifferentiated embryonic stem cells and expression decreases gradually after embryoid body (EB) formation.
  • ドメインThe POU-specific domain mediates interaction with PKM2.
  • 翻訳後修飾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.
  • 細胞内局在Nucleus. Expressed in a diffuse and slightly punctuate pattern.

    Secondary
    Goat IgG secondary antibody (ab28445) at 1/10000 dilution

    Predicted band size : 39 kDa
    Observed band size : 45 kDa (why is the actual band size different from the predicted?)

    The antibody recognised a band corresponding to Oct4 in mouse and human embryonic stem cell lysates.

  • ab27985 staining Oct4 in human embryonic carcinoma cells by Flow Cytometery. Cells were fixed in paraformaldehyde and permeabilized in saponin buffer. The primary antibody was diluted 1:500 (PBS + 10% BSA) and incubated with sample for 1 hour at 4°C. A FITC conjugated Donkey polyclonal to  goat IgG, diluted 1:200 was used as secondary. The red histogram is secondary only control whilst green and blue repersents Oct4 expression in untreated and partially differentiated with 10nM Trans-Retinoic acid for 14 days.
