Serine/threonine-protein kinase PLK4 (PLK-4) is a member of the protein kinase superfamily and plays an essential role in centriole duplication. PLK-4 triggers procentriole formation on the surface of the parental centriole cylinder, leading to the recruitment of centriole biogenesis proteins. It may be involved in tumorigenesis since centrosome aberrations are frequently observed in tumors. PLK-4 may also be involved in trophoblast differentiation by phosphorylating HAND1, leading to the disruption between HAND1 and MDFIC and then activating HAND1.

Formation of one procentriole next to each pre-existing centriole is essential for centrosome duplication, robust bipolar spindle assembly and maintenance of genome integrity. However, the mechanisms maintaining strict control over centriole copy number are incompletely understood. Here we show that
The centriole is the microtubule-based backbone that ensures integrity, function, and cell cycle-dependent duplication of centrosomes. Mostly unclear mechanisms control structural integrity of centrioles. Here, we show that the centrosome protein CEP350 functions as scaffold that coordinates distal-end properties of
At the onset of procentriole formation, a structure called the cartwheel is formed adjacent to the pre-existing centriole. SAS-6 proteins are thought to constitute the hub of the cartwheel structure. However, the exact function of the cartwheel in the process
Polo-like kinases (PLK) are eukaryotic regulators of cell cycle progression, mitosis and cytokinesis; PLK4 is a master regulator of centriole duplication. Here, we demonstrate that the SCL/TAL1 interrupting locus (STIL) protein interacts via its coiled-coil region (STIL-CC) with PLK4 in
The number of centrioles is tightly controlled to ensure bipolar spindle assembly, which is a prerequisite to maintain genome integrity. However, our understanding of the fundamental principle that governs the formation of a single procentriole per parental centriole is incomplete.
