Ubiquitin-protein ligase that probably functions as an E3 ligase in conjunction with specific E1 and E2 ligases. May also function as an E4 ligase mediating the assembly of polyubiquitin chains on substrates ubiquitinated by another E3 ubiquitin ligase. Mediates 'Lys-48'-linked polyubiquitination of substrates.

UBE4A targets PCBP1 for proteasomal degradation and that UBE4A expression can serve as a novel biomarker in thyroid cancer patients. PMID: 28963376
Ectopic overexpression of UBE4A, but not UBE3C, in cells was downregulated in vitro migration and invasion in these cells. Cumulatively, our data reveals a novel post-translational regulatory mechanism of regulating ILEI1 expression, a protein required for metastatic progression in prostate cancer cells PMID: 27862841
Identified an intestinal cDNA clone encoding ubiquitination factor E4A (UBE4A), a U-box-type ubiquitin-protein ligase. The prevalence of anti-UBE4A IgG in patients with CD was significantly higher than that in patients with UC or healthy controls PMID: 18069675
UBE4A was over-expressed in ovarian serous cystadenocarcinoma tissues, suggesting that the activity of ubiquitin-proteasome system is enhanced in ovarian cancer. PMID: 17553343
UBE4A is expressed in different tissues in a pattern that seems to be dependent from cell type and cell cycle and that UBE4A might have a specific role in different biochemical processes other than ubiquitination, including growth or differentiation. PMID: 15019985
In these studies, we define Ufd2 (a novel E4 polyubiquitylating enzyme) as a new autoantigen in scleroderma, and show that it regulates chromosome condensation and separation during mitosis in human cells. PMID: 15611659
