a kinase of the PLK family. Contains a polo-box domain (PBD), a specific phosphoserine or phosphothreonine binding domain. Substrates include BRCA2, Myt1, NudC, Cdc25C, cyclin B1, Nlp and other mitotic proteins. Inhibited by ATR. Plays a role in regulation of cytokinesis and coordinating M-phase events. Note: This description may include information from UniProtKB.
