Protein
Serine/threonine-protein kinase Nek2
Gene
NEK2
Organism
Homo sapiens (Human)
Status
Functioni
Protein kinase which is involved in the control of centrosome separation and bipolar spindle formation in mitotic cells and chromatin condensation in meiotic cells. Regulates centrosome separation (essential for the formation of bipolar spindles and high-fidelity chromosome separation) by phosphorylating centrosomal proteins such as CROCC, CEP250 and NINL, resulting in their displacement from the centrosomes. Regulates kinetochore microtubule attachment stability in mitosis via phosphorylation of NDC80. Involved in regulation of mitotic checkpoint protein complex via phosphorylation of CDC20 and MAD2L1. Plays an active role in chromatin condensation during the first meiotic division through phosphorylation of HMGA2. Phosphorylates: PPP1CC; SGO1; NECAB3 and NPM1. Essential for localization of MAD2L1 to kinetochore and MAPK1 and NPM1 to the centrosome. Phosphorylates CEP68 and CNTLN directly or indirectly (PubMed:24554434). NEK2-mediated phosphorylation of CEP68 promotes CEP68 dissociation from the centrosome and its degradation at the onset of mitosis (PubMed:25704143). Involved in the regulation of centrosome disjunction (PubMed:26220856).15 Publications
Isoform 1: Phosphorylates and activates NEK11 in G1/S-arrested cells.1 Publication
Isoform 2: Not present in the nucleolus and, in contrast to isoform 1, does not phosphorylate and activate NEK11 in G1/S-arrested cells.1 Publication
Catalytic activityi
ATP + a protein = ADP + a phosphoprotein.
Cofactori
Enzyme regulationi
Isoform 1 is inhibited by ionizing radiation in the presence of PPP1CA. Its catalytic activity is inhibited by the inhibitor CCT241950. In the presence of this inhibitor, displays an autoinhibited conformation: Tyr-70 side chain points into the active site, interacts with the activation loop, and blocks the alphaC helix.3 Publications

Involvement in diseasei
Retinitis pigmentosa 67 (RP67)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA retinal dystrophy belonging to the group of pigmentary retinopathies. Retinitis pigmentosa is characterized by retinal pigment deposits visible on fundus examination and primary loss of rod photoreceptor cells followed by secondary loss of cone photoreceptors. Patients typically have night vision blindness and loss of midperipheral visual field. As their condition progresses, they lose their far peripheral visual field and eventually central vision as well.

Expressioni
Tissue specificityi
Isoform 1 and isoform 2 are expressed in peripheral blood T-cells and a wide variety of transformed cell types. Isoform 1 and isoform 4 are expressed in the testis. Up-regulated in various cancer cell lines, as well as primary breast tumors.2 Publications
Inductioni
Expression and activity peak in the G2 phase of the mitotic cycle and decrease once the cells have entered mitosis due to degradation by the anaphase promoting complex APC/C-CDC20. In G1 phase, both isoform 1 and isoform 2 are almost undetectable. However, at the G1/S transition, there is an increase in expression of both isoforms which then remain at this increased level throughout S and G2. At the onset of mitosis, isoform 1 undergoes a rapid disappearance whereas isoform 2 continues to be present at about the same level as in G2. During the rest of mitosis, isoform 1 remains absent, while isoform 2 only begins to decline upon re-entry into the next G1 phase.2 Publications

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:| 100% | UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry. |
| 90% | UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence). |
| 50% | UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster. |
