Oct-4 (Cctamer-binding transcription factor 4) also known as Oct-3 and POU5F1 (POU domain, class 5, transcription factor 1) is a homeodomain transcription factor of the POU family class-5 subfamily. Oct-4 contains 1 homeobox DNA-binding domain and 1 POU-specific domain. Oct-4 recognizes the octamer core DNA sequence (5'-ATTTGCAT-3'). It forms a trimeric complex with SOX2 on DNA and controls the expression of a number of genes involved in embryonic development. Oct-4 is involved in the self-renewal of undifferentiated embryonic stem cells. It is frequently used as a marker for undifferentiated cells. Oct-4 expression is closely regulated; too much or too little will cause differentiation of the cells. Oct-4 has been implicated in tumorigenesis of adult germ cells. Ectopic expression of Oct-4 in adult mice has been found to cause the formation of dysplastic lesions of the skin and intestine. The intestinal dysplasia resulted from an increase in progenitor cell population and the upregulation of β-catenin transcription through the inhibition of cellular differentiation. Aberrant expression of the oct-4 gene in adult tissues is associated with tumorigenesis. It is found in a translocation with the Ewing's sarcoma gene on chromosome 21, which also leads to tumor formation. OCT4, SOX2, c-Myc and KLF4 are the 4 reprogramming factors that together are sufficient to reprogram differentiated cells to an embryonic-like state termed iPS (induced pluripotent stem) cells. iPS cells exhibit the morphology and growth properties of ES cells and express ES cell marker genes.
Gene Symbol: OCT4; POU5F1; OCT3; OTF3; OTF4; OTF-3; Oct-3; Oct-4
NCBI Gene ID: 18999
Uniprot Entry: P20263
Construct Details: Full length mouse Oct4 gene (Uniprot #P20263) is subcloned into the Lentiviral expression vector pLTE with an upstream EF1α promoter and with or without a selection marker, which can be used for both transient and stable expression in mammalian cells. It can be co-transfected with the LentiPAK DNA mix (SKU# LP-001) into HEK293 cells to produce high titer lentiviral particles. Multiple selection markers are available.
Vector Type: pLTE or pLTE-IRES-Marker (lentiviral expression vector containing a heterologous EF1α promoter which is active in both human and murine cells, see the vector map above)
Formulation: Supplied with 10 μg of endotoxin-free plasmid DNA at 200 ng/μl in sterile TE buffer (pH8.0)
Gene Insert Size: 1059 (bp)

Primers: Gene insert coding sequence can be confirmed by following primers:
(a) forward (or 5'-end) primer: 5’-CAAATGGGCGGTAGGCGTG-3’;
(b) reverse (or 3'-end) primer: 5’-CCAGGTTTCCGGGCCCTCAC-3’
Note: The sequence may vary due to the naturally occurring variants or mutations, such as single nucleotide polymorphism, or the artifact during PCR amplification. High fidelity PCR systems should always be used.
