Target

Full Name
ubiquitin like modifier activating enzyme 2
Introduction
Posttranslational modification of proteins by the addition of the small protein SUMO (see SUMO1; MIM 601912), or sumoylation, regulates protein structure and intracellular localization. SAE1 (MIM 613294) and UBA2 form a heterodimer that functions as a SUMO-activating enzyme for the sumoylation of proteins (Okuma et al., 1999 [PubMed 9920803]).

Alternative Names
Ubiquitin Like Modifier Activating Enzyme 2; Anthracycline-Associated Resistance ARX; Ubiquitin-Like 1-Activating Enzyme E1B; SUMO1 Activating Enzyme Subunit 2; SAE2; UBA2, Ubiquitin-Activating Enzyme E1 Homolog (Yeast); UBA2, Ubiquitin-Activating Enzyme E1 Homolog; Ubiquitin-Like Modifier Activating Enzyme 2; Ubiquitin-Like Modifier-Activating Enzyme 2;
Function
The heterodimer acts as an E1 ligase for SUMO1, SUMO2, SUMO3, and probably SUMO4. It mediates ATP-dependent activation of SUMO proteins followed by formation of a thioester bond between a SUMO protein and a conserved active site cysteine residue on UBA2/SAE2.

Cellular Location
Cytoplasm
Nucleus
Shuttles between the cytoplasm and the nucleus, sumoylation is required either for nuclear translocation or nuclear retention.
PTM
Sumoylated with SUMO1 and SUMO2/3 and by UBC9. Sumoylation at Lys-236 inhibits enzymatic activity. Sumoylation at the C-terminal lysine cluster plays an essential role in nuclear trafficking.
