Summary: This gene encodes a member of the ubiquitin-specific processing (UBP) family of proteases that is a deubiquitinating enzyme (DUB) with His and Cys domains. This protein is located in the cytoplasm and cleaves the ubiquitin moiety from ubiquitin-fused precursors and ubiquitinylated proteins. Mice with a mutation that results in reduced expression of the ortholog of this protein are retarded for growth, develop severe tremors by 2 to 3 weeks of age followed by hindlimb paralysis and death by 6 to 10 weeks of age. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Jul 2008]

Ubiquitin-specific protease 14 regulates ovarian cancer cisplatin-resistance by stabilizing BCL6 oncoprotein.
Title: Ubiquitin-specific protease 14 regulates ovarian cancer cisplatin-resistance by stabilizing BCL6 oncoprotein.
Data suggest that USP14 can deubiquitinate substrates distinctly of UCHL5 at the proteasome and regulates the ubiquitination of the proteasome itself which is tightly linked to its function.
Title: Inactive USP14 and inactive UCHL5 cause accumulation of distinct ubiquitinated proteins in mammalian cells.
AKT, which mediates Ser432-USP14 phosphorylation, was required for IRIF formation by USP14. Similar to USP14 block, AKT inhibition rescued the activity of NHEJ-DDR proteins in autophagy- and PTEN-deficient cells. These findings reveal a novel negative PTEN/Akt-dependent regulation of NHEJ by

USP14 negatively regulates lung tumorigenesis not only through apoptosis but also through the autophagy pathway.

USP14 can spare the substrate from degradation prior to the proteasome's commitment step, suggesting that USP14 inhibition may stimulate proteasomal degradation of undesirable proteins under certain proteotoxic conditions. This chapter describes in vitro methods to test proteasome-associated USP14 activity for substrate degradation and deubiquitylation.

USP14 levels were significantly increased in gastric cancer (GC) tissues compared to the paired normal tissues. USP14 level was an independent prognostic factor for DFS in GC patients. Its knockdown sensitized GC cells to cisplatin by triggering cisplatin-induced apoptosis via impeding Akt and ERK signaling pathways.
Title: USP14 as a novel prognostic marker promotes cisplatin resistance via Akt/ERK signaling pathways in gastric cancer.
USP14 directly interacted with RNF168, which depended on the MIU1 domain of RNF168. These findings identify USP14 as a novel substrate of autophagy and regulation of RNF168-dependent Ubiquitination and TP53BP1 recruitment by USP14 as a critical link between DNA damage repair and autophagy.

Data show that ubiquitin-specific protease 14 (USP14) is a direct target of hsa-miR-124a, and that hsa-miR-124a inhibits stemness.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
