NEK7 is a member of the NIMA family of serine/threonine kinases. In contrast to the other documented NIMA-related kinases, NEK7 harbor its catalytic domain in the C-terminus of the protein. Immunofluorescence studies suggest that NEK7 is cytoplasmic and located on chromosome 1. The major protein kinase that is active on the p70 S6 kinase hydrophobic regulatory site (FXXFS/TF/Y) Thr412, was purified from rat liver and identified as NEK7.NEK7 kinase activity is rapidly and efficiently increased by serum deprivation, and may be regulated in a cell cycle-dependent manner.

Entrance and exit from mitosis in Aspergillus nidulans require activation and proteolysis, respectively, of the NIMA (never in mitosis, gene A) serine/threonine kinase. Four different NIMA-related kinases were reported in mammals (Nek1-4), but none of them has been shown to
Current biology : CB, 11(15), 1155-1167 (2001-08-23)
The p70 S6 kinase, like several other AGC family kinases, requires for activation the concurrent phosphorylation of a site on its activation loop and a site carboxyterminal to the catalytic domain, situated in a hydrophobic motif site FXXFS/TF/Y, e.g.,Thr412 in
