Ubiquitin-like (UBL) modifiers

Ubiquitin-like (UBL) modifiers are small proteins that cells attach to other proteins to regulate their function, stability, or location. Similar to ubiquitin, UBLs modify proteins to signal processes such as degradation, transport, or activity modulation. These modifications help maintain cell health and respond to environmental changes. UBLs are involved in a variety of cellular functions and are essential for proper cell regulation, acting as molecular tags that influence how proteins behave within the cell.
