DESCRIPTION: RecName: Full=Ubiquitin D; AltName: Full=Diubiquitin; AltName: Full=Ubiquitin-like protein FAT10;
FUNCTION: Ubiquitin-like protein modifier which can be covalently attached to target protein and subsequently leads to their degradation by the 26S proteasome, in a NUB1L-dependent manner. Probably functions as a survival factor. Conjugation ability activated by UBA6. Promotes the expression of the proteasome subunit beta type-9 (PSMB9/LMP2). Regulates TNF-alpha-induced and LPS-mediated activation of the central mediator of innate immunity NF-kappa-B by promoting TNF-alpha-mediated proteasomal degradation of ubiquitinated-I-kappa-B-alpha. Required for TNF-alpha-induced p65 nuclear translocation in renal tubular epithelial cells (RTECs). May be involved in dendritic cell (DC) maturation, the process by which immature dendritic cells differentiate into fully competent antigen-presenting cells that initiate T-cell responses. Mediates mitotic non-disjunction and chromosome instability, in long-term in vitro culture and cancers, by abbreviating mitotic phase and impairing the kinetochore localization of MAD2L1 during the prometaphase stage of the cell cycle. May be involved in the formation of aggresomes when proteasome is saturated or impaired. Mediates apoptosis in a caspase-dependent manner, especially in renal epithelium and tubular cells during renal diseases such as polycystic kidney disease and Human immunodeficiency virus (HIV)- associated nephropathy (HIVAN).
SUBUNIT: Interact directly with the 26S proteasome. The interaction with NUB1L vie the N-terminal ubiquitin domain facilitates the linking of UBD-conjugated target protein to the proteasome complex and accelerates its own degradation and that of its conjugates. Interacts with the spindle checkpoint protein MAD2L1 during mitosis. Present in aggresomes of proteasome inhibited cells. Interacts with HDAC6 under proteasome impairment conditions. Forms a thioester with UBA6 in cells stimulated with tumor necrosis factor-alpha (TNFa) and interferon-gamma (IFNg).
SUBCELLULAR LOCATION: Nucleus. Cytoplasm (By similarity). Note=Accumulates in aggresomes under proteasome inhibition conditions.
TISSUE SPECIFICITY: Constitutively expressed in mature dendritic cells and B-cells. Mostly expressed in the reticuloendothelial system (e.g. thymus, spleen), the gastrointestinal system, kidney, lung and prostate gland.
INDUCTION: Rapidly degraded by the proteasome. Cell-cycle regulation with highest expression during the S-phase (at protein level). Induced during dendritic cell maturation. Negatively regulated by p53/TP53. High levels in various gastrointestinal and gynecological cancer cells. Induced in RTECs in common renal diseases including diabetic nephropathy (DN), IgA nephropathy (IgAN), and hypertensive nephrosclerosis (HN), as well as in hepatocellular carcinoma (HCC) and during HIVAN. Inducible by the proinflammatory cytokines IFNG/IFN-gamma and TNF in cancers of liver and colon. Repressed by NUB1L (at protein level).
PTM: Can be acetylated.
MISCELLANEOUS: Common types of chronic kidney disease are associated with tubulointerstitial up-regulation of FAT10. FAT10 may mediate NF-kappa-B activation and may promote tubulointerstitial inflammation in chronic kidney diseases.
SIMILARITY: Contains 2 ubiquitin-like domains.

ModBase Predicted Comparative 3D Structure on O15205
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
