2.7.11.21 polo kinaseIUBMB Comments
The enzyme associates with the spindle pole during mitosis and is thought to play an important role in the dynamic function of the mitotic spindle during chromosome segregation. The human form of the enzyme, Plk1, does not phosphorylate histone H1, enolase and phosvitin but it can phosphorylate myelin basic protein and microtubule-associated protein MAP-2, although to a lesser extent than casein .

PLK1 inhibition, together with partial inhibition of Aurora B, allows efficient spindle assembly checkpoint override to occur. This phenotype is more pronounced than the phenotype observed by combining the same PLK1 inhibitors with partial MPS1 inhibition.

physiological function
PLK1 promotes Fbw7 phosphorylation, selfubiquitination, and proteasomal degradation, creating a PLK1-Myc feedforward activation loop in MYC overexpressing tumor cells. PLK1 specifically binds to the SCFFbw7 ubiquitin ligase, phosphorylates it, and promotes its autopolyubiquitination and proteasomal degradation, counteracting Fbw7-mediated degradation of N-Myc and additional substrates, including cyclin E and Mcl1. Stabilized N-Myc in turn directly activates PLK1 transcription, constituting a positive feedforward regulatory loop that reinforces Myc-regulated oncogenic programs, association between Myc deregulation and PLK1 dependence. Analysis of the molecular mechanism responsible for reciprocal activation between Polo-like kinase-1 and N-Myc, PLK1-Fbw7-Myc signaling circuit, overview. PLK1 Reduces Fbw7 stability through promotion of its phosphorylation and autopolyubiquitination, Fbw7 turnover is mediated by autocatalytic ubiquitin transfer
physiological function
Polo-like kinase 1 (PLK1) plays many roles leading to cell division including promoting entry into, progression through and exit from mitosis. It regulates bipolar spindle formation, centrosome function and k-MT attachment in human cells. PLK1 kinase activity is required in the maintenance of a robust spindle assembly checkpoint. PLK1 kinase plays a major role in mitosis. In nocodazole-arrested U2OS cells, PLK1 activity is continuously required for maintaining Aurora B protein localisation and activity at kinetochores (Aurora B is required for the recruitment of outer kinetochore proteins). Aurora B inhibition causes PLK1 to relocalise from kinetochores into fewer and much larger foci, possibly due to incomplete recruitment of outer kinetochore proteins. PLK1 is directly involved in maintaining efficient spindle assembly checkpoint signalling, possibly by cooperating in a positive feedback loop with Aurora B, and that partially redundant mechanisms exist which reinforce the spindle assembly checkpoint. PLK1 activity appears to be required for continuous maintenance of levels of histone H3 phosphorylated at Thr3 and its accumulation at kinetochores. Upon disruption of microtubules in U2-OS cells PLK1 functions to cooperate with Aurora B to maintain a mitotic cell cycle arrest
physiological function
polo kinase 1 is essential for mitotic entry in human cells
physiological function
the enzyme is a key regulator of epithelial-to-mesenchymal transition and cell motility in normal prostate epithelium and prostate cancer. The enzyme is a potent activator of MAPK signaling
evolution
the enzyme is a member of the polo-like kinase family. Among the five members, PLK2 is the more closely related to PLK1. The overall structure of the PLK2 PBD is similar to that of the PLK1 PBD, which is composed by two polo boxes each contain b6a structures that form a 12-stranded b sandwich domain. The edge of the interface between the two polo boxes forms the phosphorylated Ser-pSer/pThr motifs binding cleft. On the hand, the peripheral regions around the core binding cleft of the PLK2 PBD is distinct from that of the PLK1 PBD, which might confer the substrate specificity of the PBDs of the polo-like kinase family. Comparison of PLK1 and PL2 substrate binding and structure, detailed overview
evolution
the polo-box domain, PBD, is unique to the five-member family of polo-like kinases, found in only Plk1, Plk2, Plk3 and Plk5. Plk4 does not have a PBD, as it has only a single polo box. Unlike the other family members, Plk5 does not contain a kinase domain

malfunction
heterozygosity of Plk4 does not lead to polyploidization and centrosome amplification
malfunction
53BP1 is excluded from the chromatin in mitotic cells and did not colocalize with gH2AX in mitotic cells after damage through irradiation. Inhibition of Plk1 by BI2536 inhibitor arrests cells in mitosis and increases the mobility of 53BP. The removal of pS1618-53BP1 modification correlates to disappearance of pS10-histone H3 as well as degradation of cyclin B and Plk1 during mitotic exit
malfunction
a failure in Plk1 regulation of the timing of CENP-Q dissociation from kinetochores leads to chromosome missegregation. Inhibition of Plk1 activity greatly diminishes hyperphosphorylates, slow-migrating PBIP1 (but not the moderately phosphorylated PBIP1 forms because of the presence of Plk1-independent phosphorylation) and appears to eliminate slow-migrating CENP-Q forms
malfunction
knockdown of Plk1 caused the reduction of telomerase activity, whereas overexpression of Plk1 increased telomerase activity. Overexpression of Plk1 leads to a significant increase of hTERT protein by prolonging its half-life but does not affect the level of hTERT mRNA

physiological function
hTERT plays a central role for telomerase activity and telomeric chromatin maintenance. Plk1 interacts with hTERT and regulates its stability. Overexpression of Plk1 up regulates the activity of telomerase. Plk1 enhances the chromatin loading of hTERT and inhibits its ubiquitination. Plk1 is a positive regulator of telomerase by enhancing the stability of hTERT, mechanism, overview. Plk1 can interact with hTERT and increase telomerase activity independently of its kinase activity
physiological function
Plk1 is a protein kinase that localizes to subcellular structures called kinetochores to promote mitotic progression. Plk1 interacts with and regulates a kinetochore-associated PBIP1-CENP-Q complex. This is a tightly regulated, cell cycle-dependent process, the deregulation of which leads to improper chromosome segregation and mitotic progression. The event is likely critical for maintaining genomic integrity and preventing aneuploidy. PBIP1 and CENP-Q are ubiquitinated in a manner that does not require Plk1. Plk1 dissociates CENP-Q from chromatin without disrupting the PBIP1-CENP-Q complex. Plk1-dependent CENP-Q phosphorylation negatively regulates the ability of the PBIP1-CENP-Q complex to associate with chromatin. Plk1 regulates the timing of CENP-Q dissociation from kinetochores. Plk1 efficiently phosphorylates and binds to the Thr78 motif of PBIP1 through a self-priming and binding mechanism and then phosphorylates the CENP-Q subunit of the PBIP1-CENP-Q complex
physiological function
polo-like kinase 1 (Plk1) is a core regulator of mitosis required for centrosome maturation, bipolar spindle formation, chromosome arm resolution, chromosome alignment and segregation, and cytokinesis. Protein kinase signaling along the kinetochore-centromere axis is crucial to assure mitotic fidelity. Deep within the centromere, Plk1 operates to assure proper chromosome alignment and segregation. Plk1 is recruited to the outer kinetochore by Bub1, NudC, and BubR1, where it phosphorylates BubR1 and CLASP to stabilize kinetochore-microtubule attachments, promoting chromosome alignment, and Kif2b to correct microtubule attachment errors, facilitating accurate chromosome segregation. At the inner kinetochore, Plk1's role in chromosome alignment and segregation also requires recruitment by and phosphorylation of CENP-U/50 (also called PBIP) and CENP-Q. Plk1 operates in pools within the kinetochore and the bulk pool is at the inner kinetochore/centromere, and it operates at chromatin and in the inner centromere in a manner that is distinct and separable from Plk1s role in stabilizing microtubule attachments at the outer kinetochore
physiological function
polo-like kinase 1 inhibits DNA damage response during mitosis, and Plk1 activity supresses DNA repair in mitotic cells. 53BP1 facilitates repair of DNA lesions through NHEJ especially when localized in the heterochromatin or at telomeres and is phosphorylated by Plk1 in mitosis, Upon phosphorylation of the N-terminal domain by ATM, 53BP1 recruits RIF1 and PTIP that block resection of DNA ends and promote repair through NHEJ. 53BP1 is recruited to the DNA damage foci through binding of its Tudor domain to the dimethylated histone H4K20-me2 and therefore 53BP1 is then recognized as a bivalent reader of posttranslationally modified mononucleosomes. Distinct behavior of 53BP1 in interphase and mitotic cells due to its phosphorylation. 53BP1 phosphorylation by Plk1 impairs its binding to ubiquitinated histones and localization to foci
physiological function
polo-like kinase 2 (PLK2) is a crucial regulator in cell cycle progression, DNA damage response, and neuronal activity
physiological function
the mitotic centromere-associated kinesin (MCAK), a potent microtubule depolymerase, is involved in regulating microtubule dynamics. The activity and subcellular localization of MCAK are tightly regulated by key mitotic kinases, such as Polo-like kinase 1 (Plk1) by phosphorylating multiple residues in MCAK. Plk1 phosphorylates very often different residues of substrates at different stages. Residue S621 in MCAK is the major phosphorylation site of Plk1, which is responsible for regulating MCAK's degradation by promoting the association of MCAK with APC/C_Cdc20. Plk1 also phosphorylates S632/S633 and regulates its catalytic activity in mitosis, this phosphorylation is required for proper spindle assembly during early phases of mitosis
physiological function
the Plk1 polo-box domain is involved in substrate binding and in determining the correct subcellular localization of Plk1, with phospho-dependent substrate recognition by the PBD being necessary for proper mitotic progression. Binding of Plk1 to PBIP1 mediates centromeric localization of Plk1 and is important for chromosome segregation
