Neuronal migration protein doublecortin

Gene

Dcx

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: -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 (PubMed:15099191, PubMed:22807455).By similarity2 Publications
Ubiquitinated by MDM2, leading to its degradation by the proteasome (PubMed:25088421). Ubiquitinated by MDM2 and subsequent degradation leads to reduce the dendritic spine density of olfactory bulb granule cells (PubMed:25088421).1 Publication

In neonatal tissues, highly expressed in brain, but not expressed in heart, liver, kidney and spleen. In adult tissues, faintly expressed in brain but not expressed in muscle, heart, lung, liver, spleen, intestine, kidney, testis and placenta.

Developmental stagei

Already expressed by embryonic day 11 (E11), maximally around birth, expression decreasing gradually during the second postnatal week, with no expression in adult stages.
