Function

Transcriptional activator that binds and transactivates ETS sequences containing the consensus nucleotide core sequence GGA[AT]. Acts synergistically with POU2F3 to transactivate the SPRR2A promoter and with RUNX1 to transactivate the ANGPT1 promoter. Also transactivates collagenase, CCL20, CLND7, FLG, KRT8, NOS2, PTGS2, SPRR2B, TGFBR2 and TGM3 promoters. Represses KRT4 promoter activity. Involved in mediating vascular inflammation. May play an important role in epithelial cell differentiation and tumorigenesis. May be a critical downstream effector of the ERBB2 signaling pathway. May be associated with mammary gland development and involution. Plays an important role in the regulation of transcription with TATA-less promoters in preimplantation embryos, which is essential in preimplantation development (By similarity). {ECO:0000250}.

Subcellular Localization

Cytoplasm {ECO:0000269PubMed:10391676, ECO:0000269PubMed:15169914, ECO:0000269PubMed:17060315}. Nucleus {ECO:0000255PROSITE-ProRule:PRU00237, ECO:0000269PubMed:10391676, ECO:0000269PubMed:15169914, ECO:0000269PubMed:17060315}. Note=Localizes to the cytoplasm where it has been shown to transform MCF-12A mammary epithelial cells via a novel cytoplasmic mechanism. Also transiently expressed and localized to the nucleus where it induces apoptosis in non-transformed breast epithelial cells MCF-10A and MCF-12A via a transcription-dependent mechanism. {ECO:0000269PubMed:10391676, ECO:0000269PubMed:15169914, ECO:0000269PubMed:17060315}.

Disease Associations

Tissue Specificity

Expressed exclusively in tissues containing a high content of terminally differentiated epithelial cells including mammary gland, colon, trachea, kidney, prostate, uterus, stomach and skin. {ECO:0000269PubMed:9129154, ECO:0000269PubMed:9234700, ECO:0000269PubMed:9336459, ECO:0000269PubMed:9395241}.
