Kruppel-like factor 4 (KLF4) is a member of the KLF family of transcription factors and regulates proliferation, differentiation, apoptosis and somatic cell reprogramming. Evidence also suggests that KLF4 is a tumor suppressor in certain cancers, including Colorectal cancer.[1]

In embryonic stem cells (ESCs), KLF4 has been demonstrated to be a good indicator of stem-like capacity. It is suggested that the same is true in mesenchymal stem cells (MSCs).

In humans, the protein is encoded by the KLF4 gene.[2] The KLF4 gene is conserved in chimpanzee, rhesus monkey, dog, cow, mouse, rat, chicken, zebrafish, and frog.[3]

Interactions

KLF4 has been shown to interact with CREB-binding protein.[4]

It was found that the transcription factor Klf4 present at the promoter of an enzymatic subunit of telomerase (TERT), where it formed a complex with β-catenin. Klf4 was required for accumulation of β-catenin at the Tert promoter but was unable to stimulate Tert expression in the absence of β-catenin.[5]
