NEK7 is a serine/threonine kinase with dual roles in cell cycle regulation and innate immunity. During mitosis, NEK7 promotes robust spindle formation and cytokinesis by phosphorylating microtubule-associated proteins like EML4, facilitating chromosome 1 1. However, NEK7's most critical function involves licensing NLRP3 inflammasome assembly independently of its kinase activity 2. NEK7 translocates with NLRP3 to the microtubule-organizing center (MTOC), where it unlocks NLRP3 autoinhibition through direct bipartite interactions that bridge adjacent NLRP3 subunits, promoting the NLRP3:PYCARD complex formation and caspase-1 activation 34. This interaction is facilitated by NLRP3 palmitoylation and phosphorylation at the MTOC 56. Functionally, NEK7 acts as a cellular switch enforcing mutual exclusivity between inflammasome activation and cell division: interaction with NEK9 during mitosis prevents NLRP3 engagement, suppressing inflammatory responses 23. Dysregulation of NEK7-NLRP3 signaling contributes to inflammatory diseases including gouty arthritis and sepsis, making NEK7 an attractive therapeutic target for NLRP3-driven pathologies 78.
