Activity summary

Urm1 also known as ubiquitin-related modifier 1 is a small protein with a mass of approximately 11 kDa. It belongs to the ubiquitin-like protein family and is expressed in a wide range of tissues notably in human tissues at the cellular level. Urm1 functions as a molecular tag influencing a variety of cellular processes through its conjugation to substrate proteins. It shares structural similarities with ubiquitin and employs a similar conjugation pathway involving E1-like activating enzymes.

Biological function summary

Urm1 acts in the thiolation of tRNA and as part of the ubiquitin-related modifier system which affects protein modification and signaling. It plays roles in regulating sulfur metabolism and is important in the biosynthesis of thiolated tRNAs. Urm1 is also involved in oxidative stress response by being part of a complex that modifies proteins in reaction to environmental stressors. As a result Urm1 impacts cellular homeostasis and the stability of various proteins within the cell.

Pathways

Urm1 influences the tRNA modification pathway an important mechanism for proper protein synthesis and function. It also participates in the cellular response to oxidative stress primarily through its interaction with cellular signaling proteins such as ROS-responsive transcription factors. In these pathways Urm1-related conjugations modify proteins affecting their activity during cellular defense mechanisms and the maintenance of protein structure under stress conditions.

Associated diseases and disorders

Urm1 impacts conditions related to cellular redox states such as cancer and neurodegenerative disorders. Aberrant regulation of Urm1 and its pathways can lead to increased oxidative stress and faulty protein synthesis contributing to these diseases. Urm1's interaction with other proteins such as p53 in tumorigenesis highlights its relevance in the cellular processes that when deregulated can lead to cancer progression. In neurodegenerative diseases diminished Urm1 function can result in the accumulation of misfolded proteins exacerbating disease phenotypes.
