Serine/threonine-protein kinase Nek3 (NEK3)

Protein kinase which affects neuronal morphogenesis and polarity through effects on microtubules. Regulates microtubule acetylation in neurons.

Contributes to prolactin- mediated phosphorylation of PXN and VAV2. Implicated in prolactin- mediated cytoskeletal reorganization and motility of breast cancer cells through mechanisms involving RAC1 activation and phosphorylation of PXN and VAV2.
