    SUMO Modification Analysis Service

      The Small Ubiquitin-like Modifier (SUMO) is an important post-translational modification that proteins undergo, involving the covalent attachment of a small, ubiquitin-like modifier to target proteins. SUMO proteins, typically about 100 amino acids in length and structurally similar to ubiquitin, have four main versions identified in mammals, from SUMO 1 to SUMO 4.


      The process known as sumoylation is a critical and widespread post-translational modification in eukaryotic organisms that regulates various essential cellular functions. These include influencing the precise location of proteins within cells, modulating gene activity, participating in the composition of nuclear structures, combating viral invasion, and controlling cell cycle processes. The balance between sumoylation and its reverse process, desumoylation, is vital for understanding the physiological pathways and progression of many diseases. Research into this process can reveal disease mechanisms and aid in the development of new therapies and precision medicine.
