Description: POU5F1 Human Recombinant produced in E Coli is a single, non-glycosylated, Polypeptide chain containing 360 amino acids and having a molecular mass of 38.6kDa.The POU5F1 is fused to a C-terminal poly-arginine tag and purified by proprietary chromatographic techniques. Introduction: POU5F1 is a homeodomain transcription factor of the POU family, expressed in embryonic stem (ES) cells and embryonic carcinoma (EC) cells.POU5F1 is significantly involved in the signaling pathway for maintaining self-renewal and pluripotency of ES cells. POU5F1 has 2 distinct DNA binding domains which independently bind half-sites of the canonical octamer motif. This flexibility allows POU5F1 to bind with distinct DNA motifs by forming heterodimers with other transcription factors or by forming homodimers in several conformations. Human POU5F1 contains a 75aa POU specific (POUS) domain and a 60aa POU-Homeo-(POUH) domain connected by a linker region. The Human POU5F1 specifically interacts with Octamer motif ATGCAAAT. In addition, 2 proline-rich domains in the N-terminal and C-terminal regions are vital for POU5F1 transactivation. POU5F1 regulates a number of target genes and has been shown to work jointly with other transcription factors including Sox2 as well as Nanog to sustain stem cell potency and self-renewal.

This gene encodes a transcription factor containing a POU homeodomain that plays a key role in embryonic development and stem cell pluripotency. Aberrant expression of this gene in adult tissues is associated with tumorigenesis. This gene can participate in a translocation with the Ewing's sarcoma gene on chromosome 21, which also leads to tumor formation. Alternative splicing, as well as usage of alternative AUG and non-AUG translation initiation codons, results in multiple isoforms. One of the AUG start codons is polymorphic in human populations. Related pseudogenes have been identified on chromosomes 1, 3, 8, 10, and 12. [provided by RefSeq, Oct 2013]

Oct4: 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. Interacts with UBE2I and ZSCAN10. Interacts with PKM2. Interacts with WWP2. Transcriptional activity is positively regulated by PKM2. 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. Belongs to the POU transcription factor family. Class- 5 subfamily. 2 isoforms of the human protein are produced by alternative splicing. Protein type: Transcription factor; DNA-binding. Chromosomal Location of Human Ortholog: 6p21.31. Cellular Component: nucleoplasm; transcription factor complex; cytoplasm; cytosol; nucleus. Molecular Function: protein binding; miRNA binding; DNA binding; sequence-specific DNA binding; ubiquitin protein ligase binding; transcription factor activity; transcription factor binding. Biological Process: transcription from RNA polymerase II promoter; anatomical structure morphogenesis; blastocyst development; regulation of transcription, DNA-dependent; regulation of asymmetric cell division; somatic stem cell maintenance; regulation of gene expression; endodermal cell fate specification; response to wounding; positive regulation of transcription from RNA polymerase II promoter; mRNA transcription from RNA polymerase II promoter
