A majority of cancer tissues showed weak to moderate cytoplasmic immunoreactivity. Strong staining was observed in a few cases of endometrial-, ovarian- and testicular cancer.
Most cancer tissues showed weak to moderate nuclear and cytoplasmic positivity. Several testicular cancers displayed strong nucleolar immunoreactivity. A majority of
liver, gastric, renal, skin and prostate cancers were negative.
GENE INFORMATION
Gene name
UBE2E3 (HGNC Symbol)
Synonyms
UbcH9
Description
Ubiquitin-conjugating enzyme E2E 3 (HGNC Symbol)
Entrez gene 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: ubiquitin-activating enzymes, or E1s, ubiquitin-conjugating enzymes, or E2s, and ubiquitin-protein ligases, or E3s. This gene encodes a member of the E2 ubiquitin-conjugating enzyme family. The encoded protein shares 100% sequence identity with the mouse and rat counterparts, which indicates that this enzyme is highly conserved in eukaryotes. Multiple alternatively spliced transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jun 2013]
