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. Interacts with APOBEC3G in an RNA-dependent manner. Ref.7 |
| Subcellular location | Cytoplasm. Nucleus. Nucleus › PML body. Nucleus speckle. Note: Predominantly cytoplasmic. Shuttles between the nucleus and the cytoplasm in a CRM1-dependent manner. Localization to nuclear foci and speckles requires active transcription. Ref.15 |
| Tissue specificity | Widely expressed. |
| Sequence caution | The sequence BAB15092.1 differs from that shown. Reason: Erroneous initiation. The sequence BAC11194.1 differs from that shown. Reason: Erroneous initiation. |
