About UBE3B

Cytogenetic location: 12q24.11 Genomic coordinates (GRCh38): 12:109,477,634-109,547,829 (from NCBI)

This gene has 13 transcripts (splice variants), 208 orthologues, 24 paralogues and is associated with 4 phenotypes. Ubiquitous expression in thyroid (RPKM 7.7), testis (RPKM 7.5) and 25 other tissues.

Summary

The modification of proteins with ubiquitin is an important cellular mechanism for targeting abnormal or short-lived proteins for degradation. Ubiquitination involves at least three classes of enzymes: E1 ubiquitin-activating Enzymes, E2 ubiquitin-conjugating Enzymes, and E3 ubiquitin-protein ligases. This gene encodes a member of the E3 ubiquitin-conjugating Enzyme family which accepts ubiquitin from an E2 ubiquitin-conjugating Enzyme and transfers the ubiquitin to the targeted substrates. A HECT (homology to E6-AP C-terminus) domain in the C-terminus of the longer isoform of this protein is the catalytic site of ubiquitin transfer and forms a complex with E2 conjugases. Shorter isoforms of this protein which lack the C-terminal HECT domain are therefore unlikely to bind E2 Enzymes. Alternatively spliced transcript variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, Jul 2012]
