PLK4

Gene symbol: PLK4
Gene: 10733
Uniprot 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. 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 (PubMed:22020124). Phosphorylates CEP131 at 'Ser-78' and PCM1 at 'Ser-372' which is essential for proper organization and integrity of centriolar satellites (PubMed:30804208).

Overview

Each montage below shows randomly selected individual cell images for the same target gene separated by sgRNA, along with an example montage of cells expressing a non-targeting negative control sgRNA at the bottom. sgRNA labels in the montages correspond to the numbered sgRNA sequences in the gene info table above. The DNA (blue) and tubulin (green) channels are displayed by default, with gH2AX (grayscale) and actin (yellow) available using the check boxes. Channel brightness, contrast, and opacity are adjustable by clicking the arrow next to the channel name. When only one channel is selected, the display defaults to grayscale. Click the “Zoom” checkbox above the channel controls to enable image zooming (via scrolling) and panning (via click-and-drag).

The cell boxes displayed for this gene are square, 30.36 μm per side for the interphase montage and 30.36 μm per side for the mitotic montage.
