Description
Product Characteristics:
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. Required for recovery after DNA damage checkpoint and entry into mitosis. Required for kinetochore localization of BUB1B. Phosphorylates SGOL1. Required for spindle pole localization of isoform 3 of SGOL1 and plays a role in regulating its centriole cohesion function. Phosphorylates BORA, and thereby promotes the degradation of BORA. Contributes to the regulation of AURKA function. Regulates TP53 stability through phosphorylation of TOPORS. Phosphorylates NEDD1. NEDD1 phosphorylation promotes subsequent targeting of the gamma-tubulin ring complex (gTuRC) to the centrosome, an important step for spindle formation. Phosphorylates both ECT2 and RACGAP1, and thereby stimulates their interaction that is essential for the cleavage furrow formation. Promotes the central spindle recruitment of ECT2.
Subcellular location: Cytoplasm, Nucleus
Synonyms: PLK, STPK13, Serine/threonine-protein kinase PLK1, Polo-like kinase 1, PLK-1, Serine/threonine-protein kinase 13, PLK1
Target Information: human homolog catalyzes the phosphorylation of a Golgi reassembly stacking protein (GRASP65), may play a role in Golgi apparatus fragmentation and reorganization during mitosis
