|Other Names||Tumor protein 63, p63, Chronic ulcerative stomatitis protein, CUSP, Keratinocyte transcription factor KET, Transformation-related protein 63, TP63, Tumor protein p73-like, p73L, p40, p51, TP63, KET, P63, P73H, P73L, TP73L|
|Target/Specificity||The synthetic peptide sequence used to generate the antibody AP13965b was selected from the C-term region of TP63. A 10 to 100 fold molar excess to antibody is recommended. Precise conditions should be optimized for a particular assay.|
|Format||Synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml DI water for a final concentration of 1 mg/ml.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C.|
|Precautions||This product is for research use only. Not for use in diagnostic or therapeutic procedures.|
|Synonyms||KET, P63, P73H, P73L, TP73L|
|Function||Acts as a sequence specific DNA binding transcriptional activator or repressor. The isoforms contain a varying set of transactivation and auto-regulating transactivation inhibiting domains thus showing an isoform specific activity. Isoform 2 activates RIPK4 transcription. May be required in conjunction with TP73/p73 for initiation of p53/TP53 dependent apoptosis in response to genotoxic insults and the presence of activated oncogenes. Involved in Notch signaling by probably inducing JAG1 and JAG2. Plays a role in the regulation of epithelial morphogenesis. The ratio of DeltaN-type and TA*-type isoforms may govern the maintenance of epithelial stem cell compartments and regulate the initiation of epithelial stratification from the undifferentiated embryonal ectoderm. Required for limb formation from the apical ectodermal ridge. Activates transcription of the p21 promoter.|
|Tissue Location||Widely expressed, notably in heart, kidney, placenta, prostate, skeletal muscle, testis and thymus, although the precise isoform varies according to tissue type. Progenitor cell layers of skin, breast, eye and prostate express high levels of DeltaN-type isoforms. Isoform 10 is predominantly expressed in skin squamous cell carcinomas, but not in normal skin tissues|

This gene encodes a member of the p53 family oftranscription factors. An animal model, p63 -/- mice, has beenuseful in defining the role this protein plays in the developmentand maintenance of stratified epithelial tissues. p63 -/- mice haveseveral developmental defects which include the lack of limbs andother tissues, such as teeth and mammary glands, which develop as aresult of interactions between mesenchyme and epithelium. Mutationsin this gene are associated with ectodermal dysplasia, and cleftlip/palate syndrome 3 (EEC3); split-hand/foot malformation 4(SHFM4); ankyloblepharon-ectodermal defects-cleft lip/palate; ADULTsyndrome (acro-dermato-ungual-lacrimal-tooth); limb-mammarysyndrome; Rap-Hodgkin syndrome (RHS); and orofacial cleft 8. Bothalternative splicing and the use of alternative promoters resultsin multiple transcript variants encoding different proteins. Manytranscripts encoding different proteins have been reported but thebiological validity and the full-length nature of these variantshave not been determined.
