Protein

Neuronal migration protein doublecortin

Gene
Dcx, Dcn
Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

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 participate in a signaling pathway that is crucial for neuronal interaction before and during migration, possibly as part of a calcium ion-dependent signal transduction pathway. May participate along with PAFAH1B1/LIS-1 in a distinct overlapping signaling pathway that promotes neuronal migration By similarity.

Post-translational modificationi

Phosphorylation by MARK1, MARK2 and PKA regulates its ability to bind microtubules By similarity.
Phosphorylation at Ser-265 and Ser-297 seems to occur only in neonatal brain, the levels falling precipitously by postnatal day 21.
