  • FunctionThe ternary complex containing UFD1L, VCP and NPLOC4 binds ubiquitinated proteins and is necessary for the export of misfolded proteins from the ER to the cytoplasm, where they are degraded by the proteasome. The NPLOC4-UFD1L-VCP complex regulates spindle disassembly at the end of mitosis and is necessary for the formation of a closed nuclear envelope.
  • Tissue specificityExpressed at highest levels in brain, heart, skeletal muscle, kidney and fetal liver.
  • PathwayProtein degradation; proteasomal ubiquitin-dependent pathway.
  • Sequence similaritiesBelongs to the NPL4 family.
    Contains 1 RanBP2-type zinc finger.
  • DomainBinds ubiquitinated proteins via its RanBP2-type zinc finger.
  • Cellular localizationCytoplasm > cytosol. Endoplasmic reticulum. Nucleus. Associated with the endoplasmic reticulum and nuclear.

  • ICC/IF image of ab101226 stained HeLa cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab101226 at 5µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM. This antibody also gave a positive result in formaldehyde fixed (4%, 10min) Hek293, HepG2, amd MCF-7 cells at 5ug/ml.
