Recombinant Human USP53 protein

Supplementary information

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

USP53 also known as ubiquitin-specific peptidase 53 functions mechanically by removing ubiquitin molecules from protein substrates which helps control protein degradation and stability. This protein has a molecular mass of approximately 103 kDa. Expression of USP53 occurs in several tissues including the liver kidney and brain. Although it's a lesser-studied protein scientists have identified its conserved deubiquitinating activity across different species.

Biological function summary

Several studies suggest that USP53 plays a role in maintaining cellular homeostasis and intracellular signaling. It is not well-known to be a part of large enzymatic complexes like some other deubiquitinases but it still involves interaction with other cellular components. Its activity influences cellular processes by regulating ubiquitin-mediated pathways critical for signaling and protein turnover.

Pathways

USP53 participates in the ubiquitin-proteasome system an essential cellular mechanism for protein catabolism. This system works alongside other pathways like the NF-kB signaling pathway where USP53 potentially influences inflammation and immune response. It interacts with other proteins in the ubiquitin signaling network such as ubiquitin ligases highlighting its role in controlling protein fate and function within cells.

Researchers have linked USP53 to certain liver disorders and neurological diseases. Mutations or altered expression of USP53 may contribute to impaired liver function or the development of hepatic fibrosis. In the context of neurological diseases USP53 may exhibit altered activity related to neurodegenerative conditions although the exact connections require more extensive research. Researchers also study USP53 in connection with proteins such as ubiquitin ligases and other signaling molecules involved in these disorders.
