PLK1 Antibody — Downregulation of PLK1 reverses EMT and inhibits the motility of metastatic PCa cells. (A) Two metastatic PCa cell lines (DU145 and C4-2B) were infected with lentiviral shRNA constructs that target either the 3'-UTR of endogenous PLK1 (shPLK1#1) or serve as a control (shCTL). Wild-type (WT) or kinase-defective (KM) PLK1 were then re-expressed in PLK1 knockdown cells. The expression of PLK1 protein and EMT markers was determined by immunoblotting. In the PLK1 immunoblot, the lower bands show endogenous PLK1 expression and the upper bands show exogenous PLK1 expression. (B) Representative phase-contrast images of control, PLK1 knockdown cells, and PLK1 knockdown cells with re-expression of WT or KM PLK1. Scale bar = 50 µm. (C) The architecture of adherens junctions (E-cadherin) and tight junctions (JAM-A) in control cells and cells with PLK1 manipulation was evaluated by immunolabeling and confocal microscopy. Scale bar, 20 µm. (D, E) The effects of PLK1 knockdown on planar migration and invasion of PCa cells were measured by the wound healing assay (D) and Matrigel invasion assay (E), respectively. The data are presented as the mean s.e.m. *p<0.01, two-tailed Student's t-test. Scale bar, 500 µm (D), and 100 µm (E). {KD}

Target Information

PLK1 is a serine/threonine kinase that is thought to function in cell mitosis and regarded as a marker of cell proliferation. It has been found to play a critical role in carcinogenesis. Polo-like kinase proteins acts by binding and phosphorylating proteins are that already phosphorylated on a specific motif recognized by the POLO box domains. Phosphorylates BORA, BUB1B/BUBR1, CCNB1, CDC25C, CEP55, ECT2, ERCC6L, FBXO5/EMI1, FOXM1, KIF20A/MKLP2, CENPU, NEDD1, NINL, NPM1, NUDC, PKMYT1/MYT1, KIZ, PPP1R12A/MYPT1, PRC1, RACGAP1/CYK4, SGOL1, STAG2/SA2, TEX14, TOPORS, p73/TP73, TPT1 and WEE1. Plays a key role in centrosome functions and the assembly of bipolar spindles by phosphorylating KIZ, NEDD1 and NINL.

O-GlcNAcylation of myosin phosphatase targeting subunit 1 (MYPT1) dictates timely disjunction of centrosomes.

The Journal of biological chemistry

Liu C,Shi Y,Li J,Liu X,Xiahou Z,Tan Z,Chen X,Li J

37-7100 was used in Immunoprecipitation to conclude that under high O-GlcNAc levels, PLK1 is untimely activated, conducive to inopportune centrosome separation and disruption of the cell cycle. We propose that too much O-GlcNAc is equally deleterious as too little O-GlcNAc, and a fine balance between the OGT/OGA duo is indispensable for successful mitotic divisions.
