Protein attributes
| Sequence length | 1692 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | May act as a negative regulator of Ras-mediated mitogenic activity. Plays a role in ciliogenesis. |
| Catalytic activity | Protein tyrosine phosphate + H2O = protein tyrosine + phosphate. |
| Subunit structure | Interacts with GRAP2 and GRB2 By similarity. |
| Subcellular location | Nucleus By similarity. Cytoplasm By similarity. Cytoplasmic vesicle By similarity. Endosome By similarity. Cytoplasm › cytoskeleton › cilium basal body By similarity. |
| Sequence similarities | Belongs to the protein-tyrosine phosphatase family. Non-receptor class subfamily. Contains 1 BRO1 domain. Contains 2 TPR repeats. Contains 1 tyrosine-protein phosphatase domain. |
| Sequence caution | The sequence BAD32456.1 differs from that shown. Reason: Erroneous initiation. |
Ontologies
Alternative products
