WebbThe inhibitory activities of 16e on Plk1-PBD is >30-fold higher than those of PMQSpTPL. Both 16a and 16e possess excellent selectivity for Plk1-PBD over Plk2/3-PBD. Analysis of the cocrystal structure of Plk1-PBD in complex with 16a reveals that the 3-(trifluoromethyl)benzoyl group in 16a interacts with Arg516 through a π-stacking … WebbThe polo-like kinase 1 (Plk1) is an important mediator of cell cycle regulation and a recognized anti-cancer molecular target. In addition to its catalytic kinase domain (KD), Plk1 contains a polo-box domain (PBD), which engages in protein–protein interactions (PPIs) essential to proper Plk1 function.

Webb30 mars 2024 · To carry out its functions, PLK1 phosphorylates an important number of proteins that can be recognized by the so-called polo box domains . During G 2 phase, PLK1 activation is mediated by phosphorylation on its T loop by aurora A. Bora, a cofactor of this kinase, is phosphorylated by CDK1, then interacts with PLK1 and facilitates its … Webb19 dec. 2011 · GST-PLK1 1–356, GST-PLK1 1–356, K82R, and truncated GST-PCNTB mutants were purified from bacteria. PLK1 and PCNTB were mixed in a kinase assay buffer (50 mM Tris-HCl, pH 7.5, 10 mM MgCl 2, 1 mM DTT, and 5 µM ATP) with 0.25 µCi γ-[32 P]ATP for 30 min at 30°C. Plk1 is an early trigger for G2/M transition. Plk1 supports the functional maturation of the centrosome in late G2/early prophase and establishment of the bipolar spindle. Plk1 phosphorylates and activates cdc25C, a phosphatase that dephosphorylates and activates the cyclinB/cdc2 complex. Plk phosphorylates and … Visa mer Serine/threonine-protein kinase PLK1, also known as polo-like kinase 1 (PLK-1) or serine/threonine-protein kinase 13 (STPK13), is an enzyme that in humans is encoded by the PLK1 (polo-like kinase 1) gene Visa mer PLK1 consists of 603 amino acids and is 66kDa. In addition to the N-terminus kinase domain, there are two conserved polo-box regions of 30 amino … Visa mer Plk1 is considered a proto-oncogene, whose overexpression is often observed in tumor cells. Aneuploidy and tumorigenesis can also result from Visa mer PLK1 has been shown to interact with: • CHEK2, • NUDC, • PIN1, • PSMA3, Visa mer During interphase, PLK1 localizes to centrosomes. In early mitosis, it associates with mitotic spindle poles. A recombinant GFP … Visa mer PLK1 is being studied as a target for cancer drugs. Many colon and lung cancers are caused by K-RAS mutations. These cancers are dependent on PLK1. When PLK1 expression was silenced with RNA interference in cell culture, K-RAS cells were selectively … Visa mer • Polo-like kinases, the gene family that PLK1 belongs to Visa mer lincoln harbor to midtown ferry
