Ubiquitin-like domain of UBL; UBLs function by remodeling the surface of their target proteins, changing their target's half-life, enzymatic activity, protein-protein interactions, subcellular localization or other properties. At least 10 different ubiquitin-like modifications exist in mammals, and attachment of different ubls to a target leads to different biological consequences. Ubl-conjugation cascades are initiated by activating enzymes, which also coordinate the ubls with their downstream pathways.
