USP14 is made up of 494 amino acids containing a 45kDa catalytic domain at its N-terminus. It contains a ubiquitin-like (Ubl) domain at the N-terminus that associates with 19S regulatory particle (RP) 26S proteasome. This binding activates the deubiquitinating activity of the protein.
Synonyms: Anti-Deubiquitinating enzyme 14 antibody produced in rabbit; Anti-Ubiquitin carboxyl-terminal hydrolase 14 antibody produced in rabbit; Anti-Ubiquitin thioesterase 14 antibody produced in rabbit; Anti-Ubiquitin-specific-processing protease 14 antibody produced in rabbit

Application: All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

Biochem Physiol Actions: USP14 (ubiquitin specific peptidase 14) gene encodes a protein that belongs to the ubiquitin-specific processing (UBP) family of proteases. It is a proteasome-associated deubiquitinating enzyme (DUB) containing His and Cys catalytic domains. It releases ubiquitin from the proteasome targeted ubiquitinated proteins resulting in regeneration of ubiquitin at the proteasome. It is involved in the degradation of chemokine receptor CXCR4. CXCR4 is required for CXCL12-induced cell chemotaxis and its overexpression leads to cancer and inflammatory and neurodegenerative disorders. Under ER stress, It binds to a, a endoplasmic reticulum (ER) stress receptor, that is involved in unfolded protein response (UPR), a mechanism to control the accumulation of unfolded proteins within the (ER) lumen. Its overexpression leads to ER-associated degradation (ERAD) pathway inhibition.
