ID:IRF6_HUMAN DESCRIPTION: RecName: Full=Interferon regulatory factor 6; Short=IRF-6; FUNCTION: Probable DNA-binding transcriptional activator. Key determinant of the keratinocyte proliferation-differentiation switch involved in appropriate epidermal development (By similarity). Plays a role in regulating mammary epithelial cell proliferation (By similarity). May regulate WDR65 transcription (By similarity). SUBUNIT: Interacts with SERPINB5. INTERACTION: Q02556:IRF8; NbExp=3; IntAct=EBI-6115643, EBI-2866563; SUBCELLULAR LOCATION: Nucleus (Potential). Cytoplasm. Note=Translocates to nucleus in response to an activating signal (By similarity). TISSUE SPECIFICITY: Expressed in normal mammary epithelial cells. Expression is reduced or absent in breast carcinomas. PTM: Phosphorylated. Phosphorylation status depends on the cell cycle and is a signal for ubiquitination and proteasome-mediated degradation. DISEASE: Defects in IRF6 are the cause of van der Woude syndrome type 1 (VWS1) [MIM:119300]. An autosomal dominant developmental disorder characterized by lower lip pits, cleft lip and/or cleft palate. Penetrance is incomplete. Van der Woude and popliteal pterygium syndrome are allelic disorders. DISEASE: Defects in IRF6 are the cause of popliteal pterygium syndrome (PPS) [MIM:119500]. PPS is an autosomal dominant developmental disorder characterized by cleft lip and/or cleft palate, and skin and genital anomalies. Penetrance is incomplete and expressivity is variable. It shows orofacial phenotypic similarities with van der Woude syndrome. Van der Woude and popliteal pterygium syndrome are allelic disorders. DISEASE: Genetic variation in IRF6 is associated with non- syndromic orofacial cleft type 6 (OFC6) [MIM:608864]; also called non-syndromic cleft lip with or without cleft palate 6. Non- syndromic orofacial cleft is a common birth defect consisting of cleft lips with or without cleft palate. Cleft lips are associated with cleft palate in two-third of cases. A cleft lip can occur on one or both sides and range in severity from a simple notch in the upper lip to a complete opening in the lip extending into the floor of the nostril and involving the upper gum. SIMILARITY: Belongs to the IRF family. SIMILARITY: Contains 1 IRF tryptophan pentad repeat DNA-binding domain.

The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
