== Disease ==
[https://www.uniprot.org/uniprot/HUWE1_HUMAN HUWE1_HUMAN] Defects in HUWE1 are the cause of mental retardation syndromic X-linked Turner type (MRXST) [MIM:[https://omim.org/entry/300706 300706]; also known as mental retardation and macrocephaly syndrome. MRXST shows clinical variability. Associated phenotypes include macrocephaly and variable contractures.  A chromosomal microduplication involving HUWE1 and HSD17B10 is the cause of mental retardation X-linked type 17 (MRX17) [MIM:[https://omim.org/entry/300705 300705]; also known as mental retardation X-linked type 31 (MRX31). Mental retardation is characterized by significantly sub-average general intellectual functioning associated with impairments in adaptative behavior and manifested during the developmental period. In contrast to syndromic or specific X-linked mental retardation which also present with associated physical, neurological and/or psychiatric manifestations, intellectual deficiency is the only primary symptom of non-syndromic X-linked mental retardation.<ref>PMID:18252223</ref> 
== Function ==
[https://www.uniprot.org/uniprot/HUWE1_HUMAN HUWE1_HUMAN] E3 ubiquitin-protein ligase which mediates ubiquitination and subsequent proteasomal degradation of target proteins. Regulates apoptosis by catalyzing the polyubiquitination and degradation of MCL1. Mediates monoubiquitination of DNA polymerase beta (POLB) at 'Lys-41', 'Lys-61' and 'Lys-81', thereby playing a role in base-excision repair. Also ubiquitinates the p53/TP53 tumor suppressor and core histones including H1, H2A, H2B, H3 and H4. Binds to an upstream initiator-like sequence in the preprodynorphin gene. Regulates neural differentiation and proliferation by catalyzing the polyubiquitination and degradation of MYCN. May regulate abundance of CDC6 after DNA damage by polyubiquitinating and targeting CDC6 to degradation.<ref>PMID:15989956</ref> <ref>PMID:15989957</ref> <ref>PMID:15767685</ref> <ref>PMID:15567145</ref> <ref>PMID:17567951</ref> <ref>PMID:18488021</ref> <ref>PMID:19713937</ref>
