CC -!- FUNCTION: Transcription factor; can act both as activator and as CC repressor. Binds the 5'-CACCC-3' core sequence. Binds to the CC promoter region of its own gene and can activate its own CC transcription. Regulates the expression of key transcription CC factors during embryonic development. Plays an important role in CC maintaining embryonic stem cells, and in preventing their CC differentiation. Required for establishing the barrier function of CC the skin and for postnatal maturation and maintenance of the CC ocular surface. Involved in the differentiation of epithelial CC cells and may also function in skeletal and kidney development. CC Contributes to the down-regulation of p53/TP53 transcription (By CC similarity). {ECO:0000250}. CC -!- SUBUNIT: Interacts with MUC1 (via the C-terminal domain) (By CC similarity). Interacts with POU5F1/OCT4 and SOX2. Interacts with CC MEIS2 isoform MeisD and PBX1 isoform PBX1a. {ECO:0000250, CC ECO:0000269|PubMed:19816951, ECO:0000269|Ref.17}. CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:10431239}. CC -!- TISSUE SPECIFICITY: Highest expression in the colon. Lower levels CC in testis, lung and small intestine. CC -!- INDUCTION: By interferon-gamma in Stat1-dependent manner. CC {ECO:0000269|PubMed:12441126}. CC -!- DISRUPTION PHENOTYPE: Death shortly after birth due to loss of CC epidermal barrier function resulting from perturbation of late- CC stage epidermal differentiation structures including the cornified CC envelope. When selectively deleted in the surface ectoderm-derived CC structures of the eye, embryos develop normally and adults are CC viable and fertile but mutants display down-regulation of Krt12 CC and Aqp5 and multiple ocular defects including corneal epithelial CC fragility, stromal edema, defective lens and loss of conjunctival CC goblet cells. {ECO:0000269|PubMed:10431239, CC ECO:0000269|PubMed:17060454}. CC -!- BIOTECHNOLOGY: POU5F1/OCT4, SOX2, MYC/c-Myc and KLF4 are the four CC Yamanaka factors. When combined, these factors are sufficient to CC reprogram differentiated cells to an embryonic-like state CC designated iPS (induced pluripotent stem) cells. iPS cells exhibit CC the morphology and growth properties of ES cells and express ES CC cell marker genes. {ECO:0000269|PubMed:16904174, CC ECO:0000269|PubMed:19816951}. CC -!- SIMILARITY: Belongs to the krueppel C2H2-type zinc-finger protein CC family. {ECO:0000305}. CC -!- SIMILARITY: Contains 3 C2H2-type zinc fingers. CC {ECO:0000255|PROSITE-ProRule:PRU00042}.
