Webb10 aug. 2015 · PLK1 plays multiple functions in mitotic progression; thus, it is important to understand the mechanism by which PLK1 is recruited to the kinetochores. Webb6 mars 2024 · Polo-like kinase 1 (Plk1) is a crucial regulator of cell cycle progression; but the mechanism of regulation of Plk1 activity is not well understood. We present evidence that Plk1 activity is controlled by a balanced methylation and phosphorylation switch.

A closer look at the muscle satellite cells revealed the source of the problem. Without PLK1, the cells got stuck part way through their cell cycle, just before they were due to divide. Webb1 aug. 2002 · Plk1 antibody injection decreased the germinal vesicle breakdown rate and distorted MI spindle organization. Our results indicate that Plk1 is a pivotal regulator of microtubule organization during mouse oocyte meiosis, fertilization, and cleavage and that its functions may be regulated by other kinases, such as staurosporine-sensitive kinases.
