| Post Translational Modifications | Ubiquitinated. 'Lys-48'-linked ubiquitinated and targeted for proteasomal degradation by the SCF(BTRC) E3 ubiquitin-protein ligase complex, thereby negatively regulating cell pluripotency maintenance and embryogenesis. Polyglutamylated by TTLL1 and TTLL4 at Glu-411, which inhibits KLF4 binding with E3 ligase component BTRC, thereby impeding ubiquitination. Deglutamylated by CCP1 and CCP6.deglutamylation promotes KLF4 ubiquitination. KLF4 glutamylation state plays a critical role in the regulation of its function in cell reprogramming, pluripotency maintenance and embryogenesis. |
| Function | Transcription factor.can act both as activator and as repressor. Binds the 5'-CACCC-3' core sequence. Binds to the promoter region of its own gene and can activate its own transcription. Regulates the expression of key transcription factors during embryonic development. Plays an important role in maintaining embryonic stem cells, and in preventing their differentiation. Required for establishing the barrier function of the skin and for postnatal maturation and maintenance of the ocular surface. Involved in the differentiation of epithelial cells and may also function in skeletal and kidney development. Contributes to the down-regulation of p53/TP53 transcription. |
