Research Backgrounds
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. Also involved in deuterosome-mediated centriole amplification in multiciliated that can generate more than 100 centrioles. Also involved in trophoblast differentiation by phosphorylating HAND1, leading to disrupt the interaction between HAND1 and MDFIC and activate HAND1. Phosphorylates CDC25C and CHEK2. Required for the recruitment of STIL to the centriole and for STIL-mediated centriole amplification.
Acetylation by KAT2A and KAT2B impairs kinase activity by shifting the kinase to an inactive conformation.
Ubiquitinated; leading to its degradation by the proteasome.
Tyrosine-phosphorylated by TEC.
Cytoplasm>Cytoskeleton>Microtubule organizing center>Centrosome>Centriole. Nucleus>Nucleolus. Cleavage furrow.
Note: Component of the deuterosome, a structure that promotes de novo centriole amplification in multiciliated cells that can generate more than 100 centrioles. Associates with centrioles throughout the cell cycle. According to PubMed:16244668, it is not present at cleavage furrows.
Homodimer (By similarity). Interacts with CEP152 (via N-terminus). Interacts with CEP78; this interaction may be important for proper PLK4 localization to the centriole and PLK4-induced overduplication of centrioles.
Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. CDC5/Polo subfamily.
