Activity summary

USP14 also known as Ubiquitin Specific Peptidase 14 is a deubiquitinating enzyme that plays a mechanical role in the ubiquitin-proteasome system. This enzyme has a molecular mass around 56 kDa and is essential for proteasome-mediated degradation activities. It is broadly expressed across many tissues but shows significant presence in the nervous system. Often people refer to USP14 as TGT in the context of certain studies or databases.

Biological function summary

USP14 functions in regulating protein turnover by removing ubiquitin from substrate proteins impacting their stability and degradation. USP14 is part of a larger protein complex associated with the proteasome specifically binding to the 19S regulatory particle. It is important in maintaining cellular protein homeostasis by editing ubiquitin chains on target proteins prior to degradation.

Pathways

USP14 participates in ubiquitin-proteasome pathways and ER-associated degradation pathway. In these processes it works closely with other proteasome proteins such as Rpn11 which also removes ubiquitin from proteins. The regulation of these pathways by USP14 directly affects protein quality control in cells influencing processes like cell cycle and stress response.

Associated diseases and disorders

USP14 has associations with neurodegenerative diseases such as Alzheimer's and Parkinson’s. It affects disease progression by modulating levels of proteins that aggregate in these conditions. Connections between USP14 and proteins such as tau and α-synuclein highlight its contribution to the pathological features seen in these disorders. Further research into USP14's role may help to uncover new therapeutic strategies for these diseases.
