KLF6 is a zinc-finger transcription factor that acts as a transcriptional activator binding GC box motifs 1. Primary functions include regulation of cellular differentiation and proliferation across multiple tissue contexts. In keratinocytes, KLF6 maintains cell proliferation and suppresses inflammation and senescence during skin aging 2. KLF6 regulates melanosome maturation and pigmentation in melanocytes 3, and in early embryonic development, it participates in a BMP4/Nodal-KLF6 axis controlling trophectoderm epithelial morphogenesis 4. In hematopoietic stem cells, KLF6 downregulation impairs differentiation and increases colony-forming potential, suggesting its role in maintaining normal hematopoietic function 5. Mechanistically, KLF6 transcriptionally regulates QKI-5 expression to suppress TGF-β signaling and epithelial-mesenchymal transition in lung adenocarcinoma 6. In diabetic kidney disease, podocyte-specific KLF6 induction triggers ApoJ secretion to activate CaMK1D signaling in proximal tubules, attenuating disease progression 1. KLF6 also regulates macrophage polarization through STAT3 signaling, with therapeutic implications for liver fibrosis 7. In intestinal immunity, KLF6 expression in pathogenic T cells promotes epithelial transformation through T-BET-dependent mechanisms 8. Clinically, KLF6 dysregulation associates with multiple cancers and age-related diseases.
