N2 - A key feature of the polycystic kidney diseases is aberrant cell proliferation, a consequence of dysfunctional ciliary signaling. The NIMA-related kinases (Nek) Nek1 and Nek8 carry the causal mutations of two of the eight established mouse models of polycystic kidneys. Nek proteins have roles in cell cycle and may contribute to coordinate regulation of cilia and cell-cycle progression. Herein is reported that in a mouse kidney epithelial cell line, mNek1 localizes to centrosomes in interphase and remains associated with the mitotic spindle pole during mitosis. In contrast, mNek8 localizes to the proximal region of the primary cilium and is not observed in dividing cells. Knockdown of mNek8 by siRNA does not affect ciliary assembly. Taken together with the phenotypes of the mutant mice, these data suggest that mNek1 and mNek8 provide links between cilia, centrosomes, and cell-cycle regulation.
