comment
  • FUNCTION Protein kinase which plays an important role in mitotic cell cycle progression (PubMed:17101132, PubMed:19941817, PubMed:31409757). Required for microtubule nucleation activity of the centrosome, robust mitotic spindle formation and cytokinesis (PubMed:17586473, PubMed:19414596, PubMed:19941817, PubMed:26522158, PubMed:31409757). Phosphorylates EML4 at 'Ser-146', promoting its dissociation from microtubules during mitosis which is required for efficient chromosome congression (PubMed:31409757). Phosphorylates RPS6KB1 (By similarity). Acts as an essential activator of the NLRP3 inflammasome assembly independently of its kinase activity (PubMed:26642356, PubMed:36442502, PubMed:39173637). Acts by unlocking NLRP3 following NLRP3 tranlocation into the microtubule organizing center (MTOC), relieving NLRP3 autoinhibition and promoting formation of the NLRP3:PYCARD complex, and activation of CASP1 (PubMed:26642356, PubMed:31189953, PubMed:36442502, PubMed:39173637, PubMed:40450990). Serves as a cellular switch that enforces mutual exclusivity of the inflammasome response and cell division: interaction with NEK9 prevents interaction with NLRP3 and activation of the inflammasome during mitosis (PubMed:26642356, PubMed:31189953).CATALYTIC ACTIVITY L-seryl-[protein] + ATP = O-phospho-L-seryl-[protein] + ADP + H(+)CATALYTIC ACTIVITY L-threonyl-[protein] + ATP = O-phospho-L-threonyl-[protein] + ADP + H(+)COFACTOR Binding to NEK9 stimulates its activity by releasing the autoinhibitory function of Tyr-97.SUBUNIT Monomer (PubMed:21320329). Interacts with NEK9; interaction takes place during mitosis; it relieves NEK7 autoinhibition and prevents interaction with NLRP3 (PubMed:19414596, PubMed:19941817, PubMed:26522158). Interacts with ANKS3; this interaction alters the subcellular distribution of NEK7 by preventing its nuclear translocation (PubMed:26188091). Interacts (via N-terminus) with NLRP3 (via LRR repeat domain); the interaction is required for the formation of the complex NLRP3:PYCARD, oligomerization of PYCARD and activation of CASP1 (PubMed:31189953, PubMed:36442502).SUBUNIT (Microbial infection) Interacts with human cytomegalovirus protein US18; this interaction promotes inflammasome assembly.INTERACTION Present at centrosome throughout the cell cycle (PubMed:17586473). Also detected at spindle midzone of the anaphase cells and eventually concentrates at the midbody (PubMed:17586473). Interaction with ANKS3 prevents its translocation to the nucleus (By similarity).ALTERNATIVE PRODUCTS Highly expressed in lung, muscle, testis, brain, heart, liver, leukocyte and spleen. Lower expression in ovary, prostate and kidney. No expression seen in small intestine.DOMAIN Displays an autoinhibited conformation: Tyr-97 side chain points into the active site, interacts with the activation loop, and blocks the alphaC helix. The autoinhibitory conformation is released upon binding with NEK9.DOMAIN The NTE (N-terminal extension) motif is a structural component of the catalytic domain and thus contributes to activity.PTM Phosphorylation at Ser-195 required for its activation.SIMILARITY Belongs to the protein kinase superfamily. NEK Ser/Thr protein kinase family. NIMA subfamily.
