Function

This gene encodes a member of the Kruppel-like factor subfamily of zinc finger proteins. Since the protein localizes to the nucleus and binds the epidermal growth factor response element, it is thought to be a transcription factor.

Interactions

KLF5 has been shown to interact with Protein SET.

Clinical significance

KLF5 expression has been linked to higher survival rates for lung cancer patients.
