WebJun 4, 2024 · Post-translational modification (PTMs) of proteins by ubiquitin and ubiquitin-like modifiers such as interferon-stimulated gene 15 (ISG15) and small ubiquitin-related modifier (SUMO) play a critical role in the regulation of brain pathophysiology. Protein ISGylation is a covalent attachment of ISG15 to its target proteins, which is a unique PTM … WebAbstract. Background: ISGylation is the conjugation of ISG15 with target proteins.ISGylation occurs through an enzymatic cascade, which is similar to that of ubiquitination. Through ISGylation, ISG15 can bind to proteins involved in cell proliferation and differentiation, thus promoting genesis and progression of malignancies.
