Neuronal migration protein doublecortin (DCX)

Microtubule-associated protein required for initial steps of neuronal dispersion and cortex lamination during cerebral cortex development. May act by competing with the putative neuronal protein kinase DCLK1 in binding to a target protein.

May in that way take part in a signaling pathway that is crucial for neuronal interaction before and during migration, maybe as part of a calcium ion-dependent signal transduction pathway. May be a part with PAFAH1B1/LIS-1 of overlapping, but distinct, signaling pathways that promote neuronal migration.
