General annotation (Comments)
| Function | Protein kinase which plays an important role in the G2/M checkpoint response to DNA damage. Controls degradation of CDC25A by directly phosphorylating it on residues whose phosphorylation is required for BTRC-mediated polyubiquitination and degradation. Ref.1 Ref.8 Ref.9 |
| Catalytic activity | |
| Cofactor | |
| Enzyme regulation | Autorepressed by intramolecular binding of the C-terminus which dissociates following phosphorylation by NEK2 isoform 1 in G1/S-arrested cells. NEK2 isoform 2 is largely not present in the nucleolus, and does not appear to phosphorylate NEK11. Activated in response to DNA damage. Inhibited by zinc. Ref.1 Ref.7 |
| Subunit structure | |
| Subcellular location | Nucleus. Nucleus › nucleolus. Note: Nuclear during interphase but moves to the polar microtubules during prometaphase and metaphase. Accumulates in the nucleolus in G1/S-arrested cells. Ref.1 Ref.7 |
| Tissue specificity | Poorly expressed in cerebellum, trachea, lung, appendix, and uterus. Ref.1 |
| Developmental stage | Predominantly expressed at S/G2/M phase. Ref.1 |
| Post-translational modification | Phosphorylated by NEK2. Phosphorylation at Ser-273 is important for its activation. Ref.1 Ref.7 Ref.8 Ref.9 |
| Sequence similarities | Belongs to the protein kinase superfamily. NEK Ser/Thr protein kinase family. NIMA subfamily. Contains 1 protein kinase domain. |
| Sequence caution | The sequence BAB15672.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. |
