Ubiquitin-like 1-activating enzyme E1B (UBLE1B) also known as SUMO-activating enzyme subunit 2 (SAE2) is an enzyme that in humans is encoded by the UBA2 gene.
Posttranslational modification of proteins by the addition of the small protein SUMO (see SUMO1), or sumoylation, regulates protein structure and intracellular localization. SAE1 and UBA2 form a heterodimer that functions as a SUMO-activating enzyme for the sumoylation of proteins.
The UBA2 cDNA fragment 2683 bp long and encodes a peptide of 640 amino acids. The predicted protein sequence is more analogous to yeast UBA2 (35% identity) than human UBA3 or E1 (in ubiquitin pathway). The UBA gene is located on chromosome 19.
Uba2 subunit is 640 aa residues long with a molecular weight of 72 kDa. It consists of three domains: an adenylation domain (containing adenylation active site), a catalytic Cys domain (containing the catalytic Cys173 residue participated in thioester bond formation), and an Ubiquitin-Like domain. SUMO-1 binds on Uba2 between the catalytic Cys domain and UbL domain.
Girl you're too sexy
come and sit with me in V.I.P.
With those curves and cocoa skin
now where have you been
The tattoo on your belly's kinda hot
