Protein attributes
| Sequence length | 1302 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is not processed. |
| Protein existence | Evidence at protein level. |
General annotation (Comments)
| Function | Binds to the ubiquitin moieties of preformed conjugates and catalyzes ubiquitin chain assembly in conjunction with E1, E2, and E3 By similarity. |
| Subunit structure | Interacts with Vcp By similarity. |
| Subcellular location | CytoplasmBy similarity. |
| Tissue specificity | Highest expression in ovary, testis, heart and skeletal muscle. Expression is low in colon, thymus and peripheral blood leukocytes. Almost undetectable in lung and spleen. |
| Post-translational modification | Proteolytically cleaved by caspases during apoptosis. Cleaved efficiently at Asp-123 by caspase-6 and granzyme B. Cleaved with approximately 10-fold less efficiency at Asp-109 by caspase-3 and caspase-7. |
| Sequence similarities | Belongs to the ubiquitin conjugation factor E4 family. Contains 1 U-box domain. |
