General annotation (Comments)
| Function | Plays an essential role in the survival of diffuse-type gastric cancer cells. Acts as a nucleolar anchoring protein for DDX47. May be involved in regulation of gene expression at the post-transcriptional level or in ribosome biogenesis in cancer cells. Ref.1 Ref.2 Ref.7 |
| Subunit structure | Interacts with the GTP form of RRAGA, RRAGC and RRAGD. Interacts with NIP7. Interacts with DDX18; the interaction is RNA-dependent. Interacts with DDX47; the interaction is RNA-dependent. Ref.2 Ref.7 |
| Subcellular location | Nucleus › nucleolus. Note: Localizes in the nucleolar-organizing region during ribosome biogenesis. Ref.1 Ref.7 |
| Tissue specificity | Expressed in various diffuse-type gastric cancers. Detected at lower levels in skeletal muscle. Ref.1 |
| Induction | Up-regulated in diffuse-type gastric cancers. Ref.1 |
| Post-translational modification | Phosphorylated Probable. Ref.1 |
| Sequence similarities | Contains 1 RRM (RNA recognition motif) domain. |
| Sequence caution | The sequence BAA91356.1 differs from that shown. Reason: Frameshift at position 1136. The sequence BAB14229.1 differs from that shown. Reason: Erroneous initiation. The sequence BAB15003.1 differs from that shown. Reason: Erroneous initiation. |
