gene geneOn this page
Summary
PCNP (PEST proteolytic signal containing nuclear protein, HGNC:30023) is a protein-coding gene on chromosome 3q12.3, encoding PEST proteolytic signal-containing nuclear protein (Q8WW12). May be involved in cell cycle regulation. It is a selective cancer dependency (DepMap: 10.8% of cell lines).
Involved in proteasome-mediated ubiquitin-dependent protein catabolic process and protein ubiquitination. Located in nuclear body.

gnomAD constraint: pLI 0.43, LOEUF 0.852, missense Z 0.422 — population loss-of-function intolerance (pLI ≥ 0.9 = LoF-intolerant; lower LOEUF = more constrained). gnomAD
Regional missense constraint (gnomAD)
ENST00000265260 splits into 4 regions with different missense tolerance; 1 is missense-constrained (≈10% of the expected missense variation). Missense variants in a constrained region (low observed/expected) are more likely to be pathogenic. gnomAD

Literature-anchored findings (GeneRIF, showing 5)
- NIRF has ubiquitination activity, the hallmark of a ubiquitin ligase. PCNP was readily ubiquitinated in 293 and COS-7 cells, and NIRF ubiquitinated PCNP in vitro as well as in vivo. (PMID:14741369)
- PCNP mediates the proliferation, migration, and invasion of human neuroblastoma cells through mitogen-activated protein kinase and PI3K/AKT/mTOR signaling pathways, implying that PCNP is a therapeutic target for patients with neuroblastoma. (PMID:29716528)
- PCNP promotes ovarian cancer progression by accelerating beta-catenin nuclear accumulation and triggering EMT transition. (PMID:32548978)
- TIPE2 and PCNP expression abnormalities in peripheral blood mononuclear cells associated with disease activity in rheumatoid arthritis: a meta-analysis. (PMID:33629294)
- PCNP is a novel regulator of proliferation, migration, and invasion in human thyroid cancer. (PMID:35813472)
