Polo-like Kinase (PLK)

(PLK)

Polo-like Kinases (PLKs) are a group of highly conserved serine/threonine protein kinases that play a key role in processes such as cell division and checkpoint regulation of mitosis. In mammals, five PLKs (PLK 1-5) encompass diverse roles in centrosome dynamics, spindle formation, intra S-phase and G2/M checkpoints, and DNA damage response.

PLKs are characterized by their Polo-box domain, which mediates protein interactions. They are additionally controlled by phosphorylation, proteolysis, and transcription, depending on the biological context. PLKs are now recognized to link cell division to developmental processes and to function in differentiated cells.
