In these studies, DCX is shown to be critical for proper nucleokinesis and cytoskeletal organization, as its microtubule‐binding properties and regulated phosphorylation (by kinases such as Cdk5, JNK, and others) enable the dynamic interaction with the microtubule network that underpins migration and process outgrowth."}, {"type": "fg", "children": [{"type": "fg_fs", "start_ref": "1", "end_ref": "6"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nAdditional work detailed in these abstracts demonstrates that DCX interacts with a spectrum of cytoskeletal and regulatory proteins—including DCLK family members, neurabin II/spinophilin, and components of the vesicular transport machinery—to coordinate aspects of polarity, dendritic development, and even axonal transport. Disruptions in DCX function or its post‐translational regulation are linked to severe malformations and neurological conditions such as lissencephaly, double cortex syndrome, and epilepsy.
