InnateDB Gene IDBG-56108 (UBE3B)
Protein Structure
UniProt Annotation
Function E3 ubiquitin-protein ligase which accepts ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfers the ubiquitin to targeted substrates. {ECO:0000250}.
Subcellular Localization
Disease Associations Blepharophimosis-ptosis-intellectual disability syndrome (BPIDS) [MIM:615057]: A disorder characterized by blepharophimosis, ptosis, mild upslanting of the palpebral fissures, epicanthus, ectodermal anomalies, developmental delay, and severe intellectual disability with absent speech. Proportionate growth retardation with a small head circumference/microcephaly, congenital malformations, muscular hypotonia, anomalies on brain imaging with hypoplasia of the corpus callosum, and low cholesterol levels are variably present. {ECO:0000269PubMed:23200864}. Note=The disease is caused by mutations affecting the gene represented in this entry.
Tissue Specificity Widely expressed. {ECO:0000269PubMed:12837265}.
