Polo-like kinase 4 shapes up.
Polo-like kinase 4 (Plk4) is a master regulator of centriole duplication and targets to centrioles through the association of its cryptic polo box domain with centriole receptors. In this issue of Structure, Shimanovskaya and colleagues unveil a new dimeric architecture of Plk4's cryptic polo box that reveals a conserved mechanism for centriole targeting of the kinase.
متن کاملPolo-like kinase 1 and Chk2 interact and co-localize to centrosomes and the midbody.
Chk2 is a protein kinase intermediary in DNA damage checkpoint pathways. DNA damage induces phosphorylation of Chk2 at multiple sites concomitant with activation. Chk2 phosphorylated at Thr-68 is found in nuclear foci at sites of DNA damage (1). We report here that Chk2 phosphorylated at Thr-68 and Thr-26 or Ser-28 is localized to centrosomes and midbodies in the absence of DNA damage. In a sea...
متن کاملNFκB regulates expression of Polo-like kinase 4
Activation of the NFκB signaling pathway allows the cell to respond to infection and stress and can affect many cellular processes. As a consequence, NFκB activity must be integrated with a wide variety of parallel signaling pathways. One mechanism through which NFκB can exert widespread effects is through controlling the expression of key regulatory kinases. Here we report that NFκB regulates ...
متن کاملPolo-like kinase 4 inhibition: a strategy for cancer therapy?
In this issue of Cancer Cell, Mason and colleagues describe the development of a Polo-like kinase 4 (PLK4) inhibitor (CFI-400945), with promising activity against tumors formed in mice from patient-derived tumor tissue. A clinical trial has been initiated, but questions remain as to whether PLK4 is the only relevant therapeutic target.
متن کاملPolo-like Kinase 2 (PLK2) Phosphorylates α-Synuclein at Serine 129 in Central Nervous System*S⃞
Several neurological diseases, including Parkinson disease and dementia with Lewy bodies, are characterized by the accumulation of alpha-synuclein phosphorylated at Ser-129 (p-Ser-129). The kinase or kinases responsible for this phosphorylation have been the subject of intense investigation. Here we submit evidence that polo-like kinase 2 (PLK2, also known as serum-inducible kinase or SNK) is a...
