Protein attributes
| Sequence length | 1058 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Activates ubiquitin by first adenylating its C-terminal glycine residue with ATP, and thereafter linking this residue to the side chain of a cysteine residue in E1, yielding an ubiquitin-E1 thioester and free AMP. |
| Pathway | |
| Subunit structure | Monomer By similarity. Interacts with GAN (via BTB domain). Ref.11 |
| Post-translational modification | ISGylated. Ref.9 |
| Involvement in disease | Spinal muscular atrophy X-linked 2 (SMAX2) [MIM:301830]: A lethal infantile form of spinal muscular atrophy, a neuromuscular disorder characterized by degeneration of the anterior horn cells of the spinal cord, leading to symmetrical muscle weakness and atrophy. Clinical features include hypotonia, areflexia, and multiple congenital contractures. |
| Miscellaneous | There are two active sites within the E1 molecule, allowing it to accommodate two ubiquitin moieties at a time, with a new ubiquitin forming an adenylate intermediate as the previous one is transferred to the thiol site. |
| Sequence similarities | Belongs to the ubiquitin-activating E1 family. |
