Rabbit Monoclonal Antibody to Sumo~2/3

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 two amino acids of the carboxy~terminus have been cleaved off. Numerous pseudogenes have been reported for this gene. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Jul 2008]
