Serine/threonine-protein kinase Nek8, also known as never in mitosis A-related kinase 8, is an enzyme that in humans is encoded by the NEK8 gene.[5][6]

## Function

[edit]

Nek8 is a member of the serine/threonine-specific protein kinase family related to NIMA (never in mitosis, gene A) of Aspergillus nidulans. The encoded protein may play a role in cell cycle progression from G2 to M phase.[5]

## Clinical significance

[edit]

Mutations in the NEK8 gene associated with nephronophthisis.[7][8]
