Protein Structure

UniProt Annotation

Function

The 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 (By similarity). {ECO:0000250}.

Subcellular Localization

Cytoplasm, cytosol {ECO:0000250}. Endoplasmic reticulum {ECO:0000250}. Nucleus {ECO:0000250}. Note=Associated with the endoplasmic reticulum and nuclear. {ECO:0000250}.

Disease Associations

Tissue Specificity

Expressed at highest levels in brain, heart, skeletal muscle, kidney and fetal liver. {ECO:0000269PubMed:11574150}.
