PLK1

A gene on chromosome 16p12.2 that encodes a member of the CDC5/Polo subfamily of serine/threonine protein kinases, which performs several key functions during the M phase of the cell cycle—e.g., regulating centrosome maturation and spindle assembly, removing cohesins from chromosome arms, inactivating anaphase-promoting complex/cyclosome (APC/C) inhibitors, and regulating mitotic exit and cytokinesis.

Molecular pathology
Defects in PLK1 are associated with gastric, thyroid and B-cell malignancies, with increased expression linked to a worse prognosis.
