Kruppel-like factor 5 (KLF5)

Target
KLF5
Molecular classification
Transcription factor
01

Overview

Kruppel-like factor 5 (KLF5) is a transcription factor that plays a role in cell proliferation and differentiation by regulating the expression of genes involved in these processes. It is known to interact with co-activators like CBP to enhance its transactivation function, and its activity can be modulated by phosphorylation. KLF5 is involved in tumorigenesis and has been implicated in the regulation of genes such as cyclin D1 and cyclin B1, which are crucial for cell cycle progression. Its expression is often increased in transformed cells and can be influenced by various signaling pathways, including oncogenic H-Ras signaling.
