特徴

• Small ubiquitin-related modifier 1, 2 and 3 (SUMO-1, -2 and -3) are members of the ubiquitin-like protein family (1).
• The covalent attachment of the SUMO-1, -2 or -3 (SUMOylation) to target proteins is analogous to ubiquitination.
• This post-translational modification is a reversible, multi-step process that is initiated by cleaving a precursor protein to a mature protein.
• Mature SUMO-1, -2 or -3 is then linked to the activating enzyme E1, conjugated to E2 and in conjunction with E3, SUMO-1, -2 or -3 is ligated to the target protein (2).
• Ubiquitin and the individual SUMO family members are all targeted to different proteins with diverse biological functions.
• Ubiquitin predominantly regulates degradation of its target (1).
• In contrast, SUMO-1 is conjugated to RanGAP, PML, p53 and IkB-alpha to regulate nuclear trafficking, formation of subnuclear structures, regulation of transcriptional activity and protein stability (3-7).
• SUMO-2/-3 forms poly-(SUMO) chains, is conjugated to topoisomerase II and APP, regulates chromosomal segregation and cellular responses to environmental stress, and plays a role in the progression of Alzheimer disease (8-11).
