Gene Information

human ... KLF4(9314)

General description

Krueppel-like factor 4, KLF4, is believed to be an stem cell marker for both embryonic stem cells and mesenchymal stem cells. KLF4 can initiate transcription of a variety of genes including PFKP and is considered a tumor suppressor gene.


Synthetic peptide directed towards the N terminal region of human KLF4

Biochem/physiol Actions

The mammalian Kruppel-like transcription factor, KLF4 is involved in preventing centrosome amplification following DNA damage caused by gamma-irradiation. It is both necessary and sufficient in preventing centrosome amplification following gamma-radiation-induced DNA damage and does so by transcriptionally suppressing cyclin E expression n. Kruppel-like factor 4 is also known to exhibit checkpoint function during the G1/S and G2/M transitions of the cell cycle.

Krüppel-like factors are transcriptional regulators that influence several cellular functions, including proliferation. Recent studies have shown that one family member, KLF4, can function both as a tumour suppressor and an oncogene. The ability of KLF4 to affect the levels of...

Krüppel-like factor 4 (KLF4) is a transcription factor that plays an important role in cell differentiation, proliferation, and survival, especially in the context of cancers. This study revealed that KLF4 activates glycolytic metabolism in breast cancer cells by up-regulating the...

The mechanisms controlling tumour-induced angiogenesis are presently not clear. In principle, angiogenesis can be achieved through the activation of endothelial cells in existing vessels or by transdifferentiation of tumour cells into endothelial cells. However, whether tumour cells can go through...
