Protein attributes
| Sequence length | 856 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level. |
General annotation (Comments)
| Function | Essential for chromosome alignment by enhancing AURKB activity (via direct CDCA8 phosphorylation) at the centromere, and for the mitotic checkpoint By similarity. Phosphorylates proteins on serine, threonine, and tyrosine. Probably associated with cell proliferation. May play some role in the control of cell proliferation or differentiation and could be involved in modulating different levels of signal transduction pathways. |
| Catalytic activity | ATP + a protein = ADP + a phosphoprotein. |
| Enzyme regulation | Inhibited by the ATP-competitive kinase inhibitor, SP600125 By similarity. |
| Tissue specificity | Present in rapidly proliferating cell lines; high levels in testis, bone marrow, spleen and thymus. Low levels in brain, heart, lung and kidney. |
| Post-translational modification | Autophosphorylated. Ref.2 |
| Sequence similarities | Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. Contains 1 protein kinase domain. |
