General description

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.

Immunogen

Linear peptide corresponding to Human PLK-4.

Application

Detect Polo Like Kinase (PLK) using this mouse monoclonal antibody, Anti-PLK-4 Antibody, clone 6H5 validated for use in western blotting, ICC & IP.
Immunocytochemistry Analysis: A representative lot detected PLK-4 in U20S cell lysates transfected with control and Cep152 siRNA, but not U2OS cell lysates transfected with PLK4 siRNA. (Cizmecioglu, O. et al. (2010). J Cell Biol. 191(4):731-739).
Immunoprecipitation Analysis: A representative lot immunoprecipitated PLK-4 in HeLa cell lysates cotransfected with Flag-tagged Gcp6 and Myc-tagged Plk-4 (Bahtz, R. et al. (2012). J Cell Sci. 125 (Pt 2): 486-496).

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

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

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 spatiotemporal mitotic processes are controlled qualitatively by phosphorylation and qualitatively by ubiquitination. Although the SKP1-CUL1-F-box protein (SCF) complex and the anaphase-promoting complex/cyclosome (APC/C) mainly mediate ubiquitin-dependent proteolysis of mitotic regulators, the E3 ligase for a large portion of mitotic

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.
