Previous GeneCards Identifiers for USP14 Gene
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]
GeneCards Summary for USP14 Gene
USP14 (Ubiquitin Specific Peptidase 14) is a Protein Coding gene. Diseases associated with USP14 include Ovarian Serous Cystadenocarcinoma and Autosomal Dominant Cerebellar Ataxia. Among its related pathways are Deubiquitination and Ubiquitin-Proteasome Dependent Proteolysis. Gene Ontology (GO) annotations related to this gene include cysteine-type endopeptidase activity and thiol-dependent ubiquitin-specific protease activity. An important paralog of this gene is USP11.
UniProtKB/Swiss-Prot Summary for USP14 Gene
Proteasome-associated deubiquitinase which releases ubiquitin from the proteasome targeted ubiquitinated proteins. Ensures the regeneration of ubiquitin at the proteasome. Is a reversibly associated subunit of the proteasome and a large fraction of proteasome-free protein exists within the cell. Required for the degradation of the chemokine receptor CXCR4 which is critical for CXCL12-induced cell chemotaxis. Serves also as a physiological inhibitor of endoplasmic reticulum-associated degradation (ERAD) under the non-stressed condition by inhibiting the degradation of unfolded endoplasmic reticulum proteins via interaction with ERN1. Indispensable for synaptic development and function at neuromuscular junctions (NMJs). Plays a role in the innate immune defense against viruses by stabilizing the viral DNA sensor CGAS and thus inhibiting its autophagic degradation.
Deubiquitinating enzymes (DUBs) are a group of proteases that catalyze the cleavage of protein-ubiquitin bonds. By removing these modifications, DUBs counteract the activity of ubiquitin ligases, which add ubiquitin molecules to target proteins.
