General description

Polo-like Kinase 1 (PLK1) is a serine/threonine-protein kinase that performs several important functions throughout M phase of the cell cycle, including the regulation of centrosome maturation and spindle assembly, the removal of cohesins from chromosome arms, the inactivation of APC/C inhibitors, and the regulation of mitotic exit and cytokinesis. Expressed PLK protein accumulates to a maximum during the G2 and M phases, declines to a nearly undetectable level following mitosis and throughout G1 phase, and then begins to accumulate again during S phase.

Specificity

This antibody recognizes phosphorylated PLK1 at Ser137.

Immunogen

KLH-conjugated linear peptide corresponding to human phosphoylated PLK1 at and around Ser137.

Application

Detect phospho-PLK1 (Ser137) using this Anti-phospho-PLK1 (Ser137) Antibody validated for use in WB.

Polo-like kinase 1 (Plk1) is pivotal for proper mitotic progression, its targeting activity is regulated by precise subcellular positioning and phosphorylation. Here we assessed the protein expression, subcellular localization and possible functions of phosphorylated Plk1 (pPlk1(Ser137) and pPlk1(Thr210)) in mouse

Polo-like kinase 1 (PLK1) is a crucial regulator of cell cycle progression. It is established that the activation of PLK1 depends on the coordinated action of Aurora-A and Bora. Nevertheless, very little is known about the spatiotemporal regulation of PLK1

Nucleic acids research, 49(13), 7554-7570 (2021-07-02)
Polo-like kinase 1 (PLK1) is a master kinase that regulates cell cycle progression. How its enzymatic activity is regulated in response to DNA damage is not fully understood. We show that PLK1 is enriched at double strand breaks (DSBs) within
