Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

USP29 also known as ubiquitin specific peptidase 29 is an enzyme involved in removing ubiquitin from proteins which impacts protein stability. It performs deubiquitination a process that regulates protein degradation cellular localization and activity. USP29 has an approximate mass of 105 kDa and shows expression across various tissues although its levels may vary depending on the tissue type and physiological conditions. Its expression pattern suggests its involvement in multiple cellular processes.

Biological function summary

Ubiquitin specific peptidase 29 plays a significant role in the regulation of the cellular protein turnover. It participates in maintaining protein homeostasis by targeting specific substrates for deubiquitination. By counteracting ubiquitination USP29 impacts cell cycle regulation and apoptosis. It is not typically part of large protein complexes but it interacts with other proteins to fulfill its functions necessary for cell viability and proper cellular function.

Pathways

USP29 can influence the p53 signaling pathway where it regulates the stability of the p53 protein an important tumor suppressor. This involvement connects it to cellular stress responses and DNA damage repair. Additionally USP29 might interact with proteins like MDM2 a known regulator of p53 to modify the levels of p53 in the cell. Interactions within such pathways point to its part in critical cellular responses associated with growth and repair mechanisms.

Abnormalities in ubiquitin specific peptidase 29 expression or function have links to cancers and neurodegenerative disorders. Its role in deubiquitinating p53 connects USP29 to tumorigenesis as dysfunctional regulation of p53 stability can contribute to cancer development particularly in colorectal and breast cancers. Furthermore studies suggest its potential involvement in neurodegenerative disorders where altered protein homeostasis affects neuronal integrity possibly acting in concert with proteins like tau notable in Alzheimer's disease.
