- Endothelial Kruppel like zinc finger protein
- Epithelial zinc finger protein EZF
FunctionTranscription 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.
Sequence similaritiesBelongs to the krueppel C2H2-type zinc-finger protein family.
Contains 3 C2H2-type zinc fingers.
Domainthe 9aaTAD motif is a transactivation domain present in a large number of yeast and animal transcription factors.
