General annotation (Comments)
| Function | Pleiotropic regulator of mitotic progression, participating in the control of spindle dynamics and chromosome separation. Phosphorylates different histones, myelin basic protein, beta-casein, and BICD2. Phosphorylates histone H3 on serine and threonine residues and beta-casein on serine residues. Important for G1/S transition and S phase progression. Phosphorylates NEK6 and NEK7 and stimulates their activity by releasing the autoinhibitory functions of Tyr-108 and Tyr-97 respectively. Ref.6 Ref.7 Ref.12 |
| Catalytic activity | ATP + a protein = ADP + a phosphoprotein. |
| Cofactor | Magnesium. |
| Enzyme regulation | Activated during mitosis by intramolecular autophosphorylation. Activity and autophosphorylation is activated by manganese >> magnesium ions. Sensitive to increasing concentration of detergents. It is not cell-cycle regulated but activity is higher in G0-arrested cells. |
| Subunit structure | Homodimer. Binds to Ran GTPase. Has a greater affinity for Ran-GDP over Ran-GTP. Interacts with NEK6, NEK7 and BICD2. Interacts with SSRP1 and SUPT16H, the 2 subunits of the FACT complex. Ref.7 Ref.9 |
| Subcellular location | |
| Tissue specificity | Most abundant in heart, liver, kidney and testis. Also expressed in smooth muscle cells and fibroblasts. |
| Developmental stage | Expression varied mildly across the cell cycle, with highest expression observed in G1 and stationary-phase cells. |
| Domain | Dimerizes through its coiled-coil domain. |
| Post-translational modification | Autophosphorylated on serine and threonine residues. When complexed with FACT, exhibits markedly elevated phosphorylation on Thr-210. During mitosis, not phosphorylated on Thr-210. Phosphorylated by CDK1 in vitro. Ref.7 |
| Sequence similarities | Belongs to the protein kinase superfamily. NEK Ser/Thr protein kinase family. NIMA subfamily. Contains 1 protein kinase domain. Contains 6 RCC1 repeats. |
| Sequence caution | The sequence AAD31936.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence BAC02704.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened. |
