+== Function ==
+[https://www.uniprot.org/uniprot/UBP14_HUMAN UBP14_HUMAN] 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).<ref>PMID:18162577</ref> <ref>PMID:19135427</ref> <ref>PMID:19106094</ref>

+== Publication Abstract from PubMed ==
+The ubiquitin-specific processing protease (UBP) family of deubiquitinating enzymes plays an essential role in numerous cellular processes. Mammalian USP14 (Ubp6 in yeast) is unique among known UBP enzymes in that it is activated catalytically upon specific association with the 26S proteasome. Here, we report the crystal structures of the 45-kDa catalytic domain of USP14 in isolation and in a complex with ubiquitin aldehyde, which reveal distinct structural features. In the absence of ubiquitin binding, the catalytic cleft leading to the active site of USP14 is blocked by two surface loops. Binding by ubiquitin induces a significant conformational change that translocates the two surface loops thereby allowing access of the ubiquitin C-terminus to the active site. These structural observations, in conjunction with biochemical characterization, identify important regulatory mechanisms for USP14.
