General annotation (Comments)
| Function | RNA binding protein, may be involved in post-transcriptional regulatory mechanisms By similarity. |
| Subcellular location | Cytoplasm By similarity. Nucleus By similarity. Note: Predominantly expressed in the cytoplasm and shuttles between the cytoplasm and the nucleus through the CRM1 export pathway By similarity. |
| Tissue specificity | Ubiquitously expressed in all the cell lines and tissues tested. Ref.1 |
| Domain | Binds RNA through its KH domains By similarity. |
| Post-translational modification | Phosphorylated By similarity. |
| Sequence similarities | Contains 2 KH domains. Contains 1 RING-type zinc finger. |
| Sequence caution | The sequence AAQ04763.1 differs from that shown. Reason: Erroneous initiation. |
