The SUMO2/3 polyclonal antibody (Cat # PAB2408) is used in Western blot to detect SUMO2/3 in HeLa cell lysate.
COS-7 cells were transfected for 24 hrs with a plasmid expressing FLAG-ERM (left panels) or FLAG-ERM KR12345 (right panels) . Untreated (-) and H2O2-treated (+) cells were collected for immunoblot analysis. Top panels : cell lysates probed by western blot (WB) with an anti-ERM antibody. Center panels : cell lysates immunoprecipitated (IP) with an anti-FLAG antibody followed by WB with SUMO1 polyclonal antibody (Cat # PAB2402) . Bottom panels : cell lysates immunoprecipitated with an anti-FLAG antibody followed by WB with SUMO2/3 polyclonal antibody (Cat # PAB2408) . (*) represents immunoprecipitated ERM-like forms recognized by anti-SUMO antibodies.
Formalin-fixed and paraffin-embedded human hepatocellular carcinoma tissue reacted with the SUMO2/3 polyclonal antibody (Cat # PAB2408) , which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry ; clinical relevance has not been evaluated. HC = hepatocarcinoma.
SUMO proteins, such as SUMO3, and ubiquitin (see MIM 191339) posttranslationally modify numerous cellular proteins and affect their metabolism and function. However, unlike ubiquitination, which targets proteins for degradation, sumoylation participates in a number of cellular processes, such as nuclear transport, transcriptional regulation, apoptosis, and protein stability (Su and Li, 2002 [PubMed 12383504]).[supplied by OMIM
OTTHUMP00000115275,SMT3 suppressor of mif two 3 homolog 1,small ubiquitin-like modifier protein 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
