Background The POU family transcription factor Oct-3/4, termed as Oct-3 or Oct-4, encoded by Pou5f1, is expressed in totipotent/pluripotent early embryonic cells. It is also expressed in embryonic stem (ES) cells and embryonal carcinoma (EC) cells, but its expression diminishes when these cells differentiate and lose pluripotency. Oct3/4 contains three functionally characterized domains, the transcriptional activation domain of N- and C-terminal region and the POU DNA-binding domain. The POU domain binds to an octamer sequence, ATTTGCAT. Several target genes of Oct3/4, such as Sox2, contains an octamer element capable of binding Oct3/4. These sites are important for transcriptional activity. Induced pluripotent stem (iPS) cells can be generated from mouse embryonic or adult fibroblasts by induction of four factors, Oct3/4, Sox2, c-Myc, and Klf4. Oct3/4 regulates a expression of Tcl1 (T cell lymphoma break point) and Nanog and contributes to cell proliferation and stabilization of cell pluripotency. Two transcription factors Oct3/4 and Sox2 works together to control a transcriptional regulatory network that regulates the expression of other essential genes.
