Functional Family Putative serine/threonine-protein kinase PLK4

Enzyme Information

2.7.11.21
Polo kinase.
based on mapping to UniProt O00444
ATP + a protein = ADP + a phosphoprotein.
-!- The enzyme associates with the spindle pole during mitosis and is thought to play an important role in the dynamic function of the mitotic spindle during chromosome segregation. -!- The human form of the enzyme, Plk1, does not phosphorylate histone H1, enolase and phosvitin but it can phosphorylate myelin basic protein and microtubule-associated protein MAP-2, although to a lesser extent than casein. -!- Formerly EC 2.7.1.37.
