Ubiquitin-like Proteins

Ubiquitin-like proteins are small molecules that attach to other proteins in the cell, functioning as signals to alter their activity, location, or lifespan. Similar to ubiquitin, these proteins help regulate cellular processes such as protein degradation, repair, and signaling pathways. They are essential for maintaining cell health and function by directing proteins to specific destinations or marking them for breakdown when necessary. Their precise action is crucial for normal biological activities and preventing diseases like cancer and neurodegeneration.
