Summary
NPLOC4 (NPL4 homolog, ubiquitin recognition factor, HGNC:18261) is a protein-coding gene on chromosome 17q25.3, encoding Nuclear protein localization protein 4 homolog (Q8TAT6). The ternary complex containing UFD1, 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. It is a common-essential gene (DepMap: required in 98.9% of cancer cell lines).
Predicted to enable ubiquitin binding activity and ubiquitin protein ligase binding activity. Predicted to contribute to K48-linked polyubiquitin modification-dependent protein binding activity and K63-linked polyubiquitin modification-dependent protein binding activity. Involved in negative regulation of RIG-I signaling pathway; negative regulation of type I interferon production; and proteolysis involved in protein catabolic process. Located in nucleus. Part of UFD1-NPL4 complex and VCP-NPL4-UFD1 AAA ATPase complex.

Literature-anchored findings (GeneRIF, showing 16)
- Ufd1-Npl4 is a negative regulator of retrotranslocation, delaying the retrotranslocation of endoplasmic reticulum-associated degradation substrates independently of its association with VCP (PMID:17331469)
- This favors the model where the Ufd1-Npl4 dimer forms a regulatory gate at the exit from the retrotranslocone, rather than actively promoting retrotranslocation like the p97VCP ATPase. (PMID:18586029)
- Data suggest that the human cytomegalovirus dislocation reaction in US2 cells is independent of the p97 cofactor Ufd1-Npl4, and different retrotranslocation mechanisms can employ distinct p97 ATPase complexes to dislocate substrates. (PMID:20702414)
- Data establish Cdc48/p97-Ufd1-Npl4 as a crucial negative regulator of Aurora B early in mitosis of human somatic cells and suggest that the activity of Aurora B on chromosomes needs to be restrained to ensure faithful chromosome segregation. (PMID:21486945)
- Data indicate that Npl4-Ufd1 heterodimer is required for VCP-FAF1 interaction. (PMID:23293021)
- In coordination with the P97-UFD1-NPL4 complex (P97(UFD1/NPL4)), NUB1L promotes transfer of NEDD8 to proteasome for degradation. (PMID:24019527)
- Data indicate that the p97-UFD1L-NPL4 protein complex specifically associates with ubiquitinated IkappaBalpha via the interactions between p97 and the SCF(beta-TRCP) ubiquitin ligase. (PMID:24248593)
- p97-Ufd1-Npl4 is an integral part of G2/M checkpoint signaling and thereby suppresses chromosome instability. (PMID:24429874)
- The study revealed a regulatory role of the p97-Npl4-Ufd1 complex in regulating a partial degradation of the NF-kappaB subunit p100. (PMID:26112410)
- We demonstrate that WT p97 can unfold proteins and that this activity is dependent on the p97 adaptor NPLOC4-UFD1L, ATP hydrolysis, and substrate ubiquitination, with branched chains providing maximal stimulation. (PMID:28512218)
- Multisystem proteinopathy mutations in VCP/p97 increase NPLOC4-UFD1L binding and substrate processing. (PMID:31623962)
- Targeting NPL4 via drug repositioning using disulfiram for the treatment of clear cell renal cell carcinoma. (PMID:32667929)
- Seesaw conformations of Npl4 in the human p97 complex and the inhibitory mechanism of a disulfiram derivative. (PMID:33402676)
- Multiple UBX proteins reduce the ubiquitin threshold of the mammalian p97-UFD1-NPL4 unfoldase. (PMID:35920641)
- Structural basis for the interaction between human Npl4 and Npl4-binding motif of human Ufd1. (PMID:36087575)
- NPLOC4 is a potential target and a poor prognostic signature in lung squamous cell carcinoma. (PMID:37993584)

Function. The ternary complex containing UFD1, 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-UFD1-VCP complex regulates spindle disassembly at the end of mitosis and is necessary for the formation of a closed nuclear envelope. Acts as a negative regulator of type I interferon production via the complex formed with VCP and UFD1, which binds to RIGI and recruits RNF125 to promote ubiquitination and degradation of RIGI.
Subunit / interactions. Heterodimer with UFD1. The heterodimer binds ubiquitinated proteins. The heterodimer binds to VCP and inhibits Golgi membrane fusion. Interacts with ZFAND2B; probably through VCP.
Subcellular location. Cytoplasm. Cytosol. Endoplasmic reticulum. Nucleus.
Tissue specificity. Expressed at highest levels in brain, heart, skeletal muscle, kidney and fetal liver.
Domain organisation. Binds ubiquitinated proteins via its RanBP2-type zinc finger.
Pathway. Protein degradation; proteasomal ubiquitin-dependent pathway.
Miscellaneous. May be due to an intron retention.
Similarity. Belongs to the NPL4 family.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 170 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
