|Product Overview :
||The active human SUMO-I (the 1-97 animo acid region of the Ubiquitin-like protein SMT3C precursor is also called Ubiquitin-homology domain protein PIC1, Ubiquitin-like protein UBL1, Ubiquitin-related protein SUMO-I, GAP modifying protein-I, GMP-I, and Sentrin-I. The enzyme contains a single polypeptide band of 11 kDa. The predicted molecular weight of hSOMO I is 11 KDa. The The final fraction of enzyme contains single polypeptide band of approximately 20 kDa on SDS PAGE.
||This gene encodes a protein that is a member of the SUMO (small ubiquitin-like modifier) protein family. It functions in a manner similar to ubiquitin in that it is bound to target proteins as part of a post-translational modification system. However, unlike ubiquitin which targets proteins for degradation, this protein is involved in a variety of cellular processes, such as nuclear transport, transcriptional regulation, apoptosis, and protein stability. It is not active until the last four amino acids of the carboxy-terminus have been cleaved off. Several pseudogenes have been reported for this gene. Alternate transcriptional splice variants encoding different isoforms have been characterized.
