Activity summary

UBA52 also known as Ubiquitin A-52 Residue Ribosomal Protein Fusion Product 1 is a protein fusion of ubiquitin and ribosomal protein L40. It has a mass of approximately 15 kDa. UBA52 expresses widely in various tissues including the liver brain and heart playing a role in protein synthesis and ubiquitination. The ubiquitin domain of UBA52 gets translated and cleaved to participate in the ubiquitin-proteasome system while the ribosomal component integrates into the 60S subunit of the ribosome.

Biological function summary

UBA52 functions as both a ribosomal protein and a source of ubiquitin. This dual role enables it to participate in protein synthesis as part of the ribosome. Additionally it provides ubiquitin required for post-translational modification of proteins affecting protein stability and degradation. UBA52 is part of the ribosome complex and contributes to efficient protein translation while its ubiquitin segment influences protein turnover and cellular response to stress.

Pathways

UBA52 plays roles in protein translation and ubiquitin-mediated proteolysis. These pathways are essential for maintaining cellular homeostasis. In the context of protein synthesis UBA52 associates with other ribosomal proteins and supports the assembly of the ribosome facilitating mRNA translation. In the ubiquitin-proteasome pathway UBA52 contributes ubiquitin moieties used to tag proteins for degradation working with E2 and E3 ligases such as UBE2K and HUWE1 important for regulated proteolysis.

Associated diseases and disorders

UBA52 is linked to conditions involving protein synthesis defects and improper protein degradation including cancer and neurodegenerative disorders. Changes in UBA52 expression or mutations can disrupt ribosome function affecting cellular proliferation and survival in cancers. Additionally impaired ubiquitin signaling has implications in neurodegenerative diseases where protein aggregates form due to faulty degradation. UBA52's connection to pathways with proteins like p53 in cancer and Parkin in neurodegeneration further illustrates its relevance across different pathologies.
