UniProt Summary: Protein kinase which influences 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. {ECO:0000269|PubMed:15618286, ECO:0000269|PubMed:17297458}.
