[https://www.uniprot.org/uniprot/P63_HUMAN P63_HUMAN] Defects in TP63 are the cause of acro-dermato-ungual-lacrimal-tooth syndrome (ADULT syndrome) [MIM:[https://omim.org/entry/103285 103285]; a form of ectodermal dysplasia. Ectodermal dysplasias (EDs) constitute a heterogeneous group of developmental disorders affecting tissues of ectodermal origin. EDs are characterized by abnormal development of two or more ectodermal structures such as hair, teeth, nails and sweat glands, with or without any additional clinical sign. Each combination of clinical features represents a different type of ectodermal dysplasia. ADULT syndrome involves ectrodactyly, syndactyly, finger- and toenail dysplasia, hypoplastic breasts and nipples, intensive freckling, lacrimal duct atresia, frontal alopecia, primary hypodontia, and loss of permanent teeth. ADULT differs significantly from EEC3 syndrome by the absence of facial clefting.  Defects in TP63 are the cause of ankyloblepharon-ectodermal defects-cleft lip/palate (AEC) [MIM:[https://omim.org/entry/106260 106260]. AEC is an autosomal dominant condition characterized by congenital ectodermal dysplasia with coarse, wiry, sparse hair, dystrophic nails, slight hypohidrosis, scalp infections, ankyloblepharon filiform adnatum, maxillary hypoplasia, hypodontia and cleft lip/palate.<ref>PMID:11159940</ref>   Defects in TP63 are the cause of ectrodactyly-ectodermal dysplasia-cleft lip/palate syndrome type 3 (EEC3) [MIM:[https://omim.org/entry/604292 604292]. EEC3 is an autosomal dominant syndrome characterized by ectrodactyly of hands and feet, ectodermal dysplasia and facial clefting.<ref>PMID:10535733</ref> <ref>PMID:10839977</ref> <ref>PMID:11462173</ref> <ref>PMID:12838557</ref>   Defects in TP63 are the cause of split-hand/foot malformation type 4 (SHFM4) [MIM:[https://omim.org/entry/605289 605289]. Split-hand/split-foot malformation is a limb malformation involving the central rays of the autopod and presenting with syndactyly, median clefts of the hands and feet, and aplasia and/or hypoplasia of the phalanges, metacarpals, and metatarsals. There is restricted overlap between the mutational spectra of EEC3 and SHFM4.<ref>PMID:10839977</ref> <ref>PMID:11462173</ref>   Defects in TP63 are the cause of limb-mammary syndrome (LMS) [MIM:[https://omim.org/entry/603543 603543]. LMS is characterized by ectrodactyly, cleft palate and mammary-gland abnormalities.<ref>PMID:11462173</ref>   Note=Defects in TP63 are a cause of cervical, colon, head and neck, lung and ovarian cancers.  Defects in TP63 are a cause of ectodermal dysplasia Rapp-Hodgkin type (EDRH) [MIM:[https://omim.org/entry/129400 129400]; also called Rapp-Hodgkin syndrome or anhidrotic ectodermal dysplasia with cleft lip/palate. Ectodermal dysplasia defines a heterogeneous group of disorders due to abnormal development of two or more ectodermal structures. EDRH is characterized by the combination of anhidrotic ectodermal dysplasia, cleft lip, and cleft palate. The clinical syndrome is comprised of a characteristic facies (narrow nose and small mouth), wiry, slow-growing, and uncombable hair, sparse eyelashes and eyebrows, obstructed lacrimal puncta/epiphora, bilateral stenosis of external auditory canals, microsomia, hypodontia, cone-shaped incisors, enamel hypoplasia, dystrophic nails, and cleft lip/cleft palate.<ref>PMID:12939657</ref> <ref>PMID:12766194</ref> <ref>PMID:15200513</ref> <ref>PMID:16740912</ref>   Defects in TP63 are the cause of non-syndromic orofacial cleft type 8 (OFC8) [MIM:[https://omim.org/entry/129400 129400]. 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.
== Function ==
[https://www.uniprot.org/uniprot/IASPP_HUMAN IASPP_HUMAN] Regulator that plays a central role in regulation of apoptosis and transcription via its interaction with NF-kappa-B and p53/TP53 proteins. Blocks transcription of HIV-1 virus by inhibiting the action of both NF-kappa-B and SP1. Also inhibits p53/TP53 function, possibly by preventing the association between p53/TP53 and ASPP1 or ASPP2, and therefore suppressing the subsequent activation of apoptosis.<ref>PMID:15489900</ref> <ref>PMID:10336463</ref> <ref>PMID:12134007</ref> <ref>PMID:12524540</ref> [https://www.uniprot.org/uniprot/P63_HUMAN P63_HUMAN] 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.<ref>PMID:9774969</ref> <ref>PMID:11641404</ref> <ref>PMID:12446779</ref> <ref>PMID:12446784</ref> <ref>PMID:12374749</ref> <ref>PMID:20123734</ref> <ref>PMID:22197488</ref>
