== Disease ==
[https://www.uniprot.org/uniprot/UBE3A_HUMAN UBE3A_HUMAN] Defects in UBE3A are a cause of Angelman syndrome (AS) [MIM:[https://omim.org/entry/105830 105830]; also known as 'happy puppet syndrome'. AS is characterized by features of severe motor and intellectual retardation, microcephaly, ataxia, frequent jerky limb movements and flapping of the arms and hands, hypotonia, hyperactivity, hypopigmentation, seizures, absence of speech, frequent smiling and episodes of paroxysmal laughter, and an unusual facies characterized by macrostomia, a large mandible and open-mouthed expression, a great propensity for protruding the tongue ('tongue thrusting'), and an occipital groove.<ref>PMID:10508479</ref> <ref>PMID:9585605</ref>
== Function ==
[https://www.uniprot.org/uniprot/UBE3A_HUMAN UBE3A_HUMAN] E3 ubiquitin-protein ligase which accepts ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and transfers it to its substrates. Several substrates have been identified including the RAD23A and RAD23B, MCM7 (which is involved in DNA replication), annexin A1, the PML tumor suppressor, and the cell cycle regulator CDKN1B. Catalyzes the high-risk human papilloma virus E6-mediated ubiquitination of p53/TP53, contributing to the neoplastic progression of cells infected by these viruses. Additionally, may function as a cellular quality control ubiquitin ligase by helping the degradation of the cytoplasmic misfolded proteins. Finally, UBE3A also promotes its own degradation in vivo.<ref>PMID:10373495</ref> <ref>PMID:19325566</ref> <ref>PMID:19233847</ref> <ref>PMID:19204938</ref> <ref>PMID:19591933</ref> <ref>PMID:22645313</ref>
