Background: The NIMA-related kinases or NEKs represents a group of protein kinases whose members have key roles in mitosis. Human cells express eleven genes that encode NEK1 to NEK11 sharing approximately 40–45% identity with NIMA kinase, the founding member of this family of Aspergillus nidulan. NEK2 is a cell cycle regulated kinase with activity low in G1, increased in S and G2, and diminished after mitotic onset. It plays a direct role in enabling bipolar spindle formation through initiating the separation of centrosomes at the G2 /M transition. Furthermore, NEK2 interacts with and phosphorylates at least two components of the intercentriolar linkage, C-Nap1 and Rootletin. Interaction of NEK2 with protein phosphatase 1 (PP1) can lead to dephosphorylation and inhibition of NEK2 kinase activity.
