General annotation (Comments)
| Function | Serine/threonine-protein kinase that plays a central role in centriole duplication. Able to trigger procentriole formation on the surface of the parental centriole cylinder, leading to the recruitment of centriole biogenesis proteins such as SASS6, CENPJ/CPAP, CCP110, CEP135 and gamma-tubulin. When overexpressed, it is able to induce centrosome amplification through the simultaneous generation of multiple procentrioles adjoining each parental centriole during S phase. Phosphorylates 'Ser-151' of FBXW5 during the G1/S transition, leading to inhibit FBXW5 ability to ubiquitinate SASS6. Its central role in centriole replication suggests a possible role in tumorigenesis, centrosome aberrations being frequently observed in tumors. Phosphorylates CDC25C and CHEK2 By similarity. Also involved in trophoblast differentiation by phosphorylating HAND1, leading to disrupt the interaction between HAND1 and MDFIC and activate HAND1. Ref.8 |
| Catalytic activity | ATP + a protein = ADP + a phosphoprotein. |
| Subunit structure | Homodimer. Interacts with CEP152 (via N-terminus) By similarity. Ref.9 |
| Subcellular location | Cytoplasm › cytoskeleton › centrosome › centriole. Nucleus › nucleolus. Cleavage furrow. Note: Associates with centrioles throughout the cell cycle. According to Ref.6, it localizes to the nucleolus during G2, to the centrosomes in G2/M, and to the cleavage furrow during cytokinesis. Ref.6 Ref.8 Ref.9 |
| Tissue specificity | expressed in tissues associated with mitotic and meiotic cell division. Highly expressed in testis. Ref.1 |
| Post-translational modification | Ubiquitinated; leading to its degradation by the proteasome. Ref.5 Tyrosine-phosphorylated by TEC By similarity. |
| Disruption phenotype | Death during embryogenesis. Embryos arrest after gastrulation at E7.5, with a marked increase in mitotic and apoptotic cells. Heterozygous mice are viable but show increased liver and lung cancers in elderly mice. Defects in heterozygous mice are associated with progressive cell cycle delays, increased spindle irregularities and accelerated hepatocellular carcinogenesis, probably due to increased centrosomal amplification, multipolar spindle formation and aneuploidy. The incidence of spontaneous. Ref.6 Ref.7 |
| Sequence similarities | Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. CDC5/Polo subfamily. Contains 1 POLO box domain. Contains 1 protein kinase domain. |
| Sequence caution | The sequence AAH51483.1 differs from that shown. Reason: Erroneous initiation. |
