What Does SUMO Stand For?

SUMO stands for Small Ubiquitin Related Modifier

SUMO, or Small Ubiquitin Related Modifier, refers to a family of protein modifiers that play a crucial role in various cellular processes, including nuclear transport, signal transduction, and the regulation of gene expression. SUMO proteins are involved in modifying target proteins through a process called SUMOylation, which can influence protein stability, localization, and activity. This post-translational modification is essential for maintaining cellular homeostasis and responding to stress, making SUMO a significant focus of research in cellular biology and pathology.
