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.

靶标
基因名
SAE1
蛋白名
SUMO-activating enzyme subunit 1
亚基
Heterodimer of SAE1 and UBA2/SAE2. The heterodimer corresponds to the two domains that are encoded on a single polypeptide chain in ubiquitin-activating enzyme E1. Interacts with UBE2I.
亚细胞定位
Nucleus.
组织特异性
Expression level increases during S phase and drops in G2 phase (at protein level).
翻译后修饰
Phosphorylated upon DNA damage, probably by ATM or ATR.
相似性
Belongs to the ubiquitin-activating E1 family.
