EC 2.7.11.21 Details
EC number
2.7.11.21
Accepted name
polo kinase
Reaction
ATP + a protein = ADP + a phosphoprotein
Other name(s)
Cdc5, Cdc5p, Plk, PLK, Plk1, Plo1, POLO kinase, polo serine-threonine kinase, polo-like kinase, polo-like kinase 1, serine/threonine-specific Drosophila kinase polo, STK21
Systematic name
ATP:protein phosphotransferase (spindle-pole-dependent)
CAS registry number
149433-93-2
Comment
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 [2].
