產(chǎn)品描述：
Like all recombinant proteins, this Recombinant Human POU5F1 protein was encoded by recombinant DNA. The recombinant DNA was introduced to a plasmid in which the gene of POU5F1 was cloned downstream of a promoter region. When the plasmid was introduced to the cells of E.coli, the E.coli’s own protein synthesis pathways would then result in the expression of the POU5F1 protein. And the next step was protein purification. The purity of this recombinant protein is 90%+ determined by SDS-PAGE.
POU Class 5 Homeobox 1 (POU5F1) is a transcription factor of the POU family that binds an octameric sequence motif to activate the expression of downstream genes. POU5F1 has been identified as one of the most important CSC markers and participates in stemness maintenance in various tumors. Published literatures have certified that increased POU5F1 was correlated with clinicopathological features and prognosis not only in LIHC, but also in bladder carcinoma, non-small cell lung carcinoma, and oral squamous cell cancer. Although many studies have been performed, the prognostic significance of POU5F1 in cancers remains controversial, and the functions of POU5F1 in the regulatory network of tumors are not fully recognized. Some studies have come to different or even totally opposite conclusions regarding the prognostic value of POU5F1 and the role of POU5F1 in tumor development. For instance, He et al. showed that elevated POU5F1 in esophageal squamous cell carcinoma symbolized poor survival outcomes. However, Ge et al. found that high expression of POU5F1 was connected with longer survival in esophageal squamous cell carcinoma. Nevertheless, POU5F1 may serve as an essential predictive factor for multiple cancers in the near future. -

功能：Transcription factor that binds to the octamer motif (5'-ATTTGCAT-3'). Forms a trimeric complex with SOX2 or SOX15 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.
