NEK7 is an essential mediator of NLRP3 inflammasome activation downstream of potassium efflux. NEK7 binds directly to the catalytic domain of NLRP3, and this interaction is promoted by K+ efflux. NEK7 loss abolishes caspase-1 activation and IL-1β release in response to NLRP3 stimuli but not AIM2 or NLRC4 stimuli. Notably, the catalytic activity of NEK7 is dispensable for NLRP3 inflammasome activation; its scaffolding role is sufficient. NEK7 is required for high-molecular-mass NLRP3 complex formation and ASC oligomerization/speck formation. |

NEK7 binds the leucine-rich repeat (LRR) domain of NLRP3 in a kinase-independent manner downstream of mitochondrial ROS induction, and this interaction is necessary for NLRP3-ASC complex formation, ASC oligomerization, and caspase-1 activation. NLRP3 inflammasome activation is restricted to interphase because NEK7 is sequestered during mitosis, making mitosis and inflammasome activation mutually exclusive. |

Cryo-EM structure of inactive human NLRP3 in complex with NEK7 at 3.8 Å resolution shows the C-terminal lobe of NEK7 nestles against both the LRR and NACHT domains of NLRP3. Mutagenesis of the NLRP3-NEK7 interface abolishes activation in vitro and in cells. Modeling predicts NEK7 bridges adjacent NLRP3 subunits in the active oligomer, and mutations to this secondary interface also abolish activation, suggesting NEK7 mediates NLRP3 oligomerization via bipartite interactions. |

Nercc1/NEK9 directly phosphorylates NEK7 (and NEK6) on the activation loop in vitro, leading to activation of NEK7 kinase activity (~20–25-fold for NEK6; similar for NEK7). NEK7 binds the C-terminal non-catalytic tail of NEK9. This establishes a mitotic kinase cascade: NEK9 → NEK7. |

Crystal structure of NEK7 reveals an autoinhibited conformation in which Tyr97 protrudes into the active site, interacts with the activation loop, and blocks the αC helix. Mutation of Tyr97 to phenylalanine renders NEK7 constitutively active. Binding of the NEK9 non-catalytic C-terminal domain increases NEK6/NEK7 activity but not the Tyr97Phe mutant activity, indicating NEK9 activates NEK7 by releasing the autoinhibitory tyrosine. |

Self-association of the NEK9 C-terminal domain (CTD) is required for NEK7 activation. Crystal structure of NEK7(Y97F) bound to NEK9(810-828) reveals a binding site on the C-lobe of NEK7. NEK7(Y97F) crystallizes as a back-to-back dimer between N-lobes; this dimer interface is coupled to the conformation of residue 97. NEK9-CTD activates NEK7 by promoting back-to-back dimerization that releases the autoinhibitory Tyr97. |

NEK6 and NEK7 are both activated in mitosis and are required for robust mitotic spindle formation. Depletion or expression of reduced-activity mutants causes metaphase arrest with fragile spindles; hypomorphic conditions cause cytokinesis defects. NEK6 localizes to spindle microtubules in metaphase/anaphase and to the midbody; NEK7 localizes primarily to spindle poles. Despite high similarity, NEK6 and NEK7 are non-redundant for mitotic progression. |
