Description
SUMO (Small Ubiquitin-like Modifier) proteins are a family of small proteins that are covalently attached to and detached from other proteins in cells to modify their function. Unlike ubiquitination which targets proteins for degradation SUMO modification plays a critical role in a number of cellular functions including nucleocytoplasmic transport gene expression cell cycle and formation of subnuclear structures such as promyelocytic leukemia (PML) bodies.
There are three confirmed SUMO isoforms in human; SUMO1 SUMO2 and SUMO3. SUMO2 /3 show a high degree of similarity to each other and are distinct from SUMO-1. Individual SUMO family members are all targeted to different proteins with diverse biological functions. SUMO-1 is conjugated to RanGAP PML p53 and IκB-α to regulate nuclear trafficking formation of subnuclear structures regulation of transcriptional activity and protein stability. SUMO1 is encoded as a 101 aa protein and first Met and C-terminal 4 aa are removed from the preprotein.
