Protein attributes
| Sequence length | 985 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level. |
General annotation (Comments)
| Function | Nucleoplasmic shuttling protein. Mediates the nuclear import of EIF4E by a piggy-back mechanism. |
| Subunit structure | Interacts with EIF4E. Interacts with importin beta only in the presence of importin alpha, suggesting a direct interaction with importin alpha. |
| Subcellular location | Cytoplasm. Nucleus. Note: Predominantly cytoplasmic. Shuttles between the nucleus and the cytoplasm in a CRM1-dependent manner. |
| Tissue specificity | Widely expressed. |
