General description

Doublecortin gene is mapped to human chromosome Xq23. It comprises two homologous doublecortin (DC) domains, one each in the N-terminal and C-terminal region. A linker connects a flexible unstructured region. The C-terminal sequences also have serine/proline-rich region.

Specificity

Anti-Doublecortin(N-terminal) specifically recognizes human, rat, and mouse Doublecortin.

Immunogen

synthetic peptide corresponding to amino acids 1-17 located at the N-terminus of rat doublecortin, conjugated to KLH. This sequence is identical in mouse, and highly conserved in human doublecortin.

Application

Anti-Doublecortin antibody produced in rabbit is suitable for immunoblotting at a working concentration of 0.5-1μg/mL using HEK-293T cells expressing human doublecortin and rat brain extract (S1 fraction), and 1-2μg/mL using mouse brain extract (S1 fraction).

Biochem/physiol Actions

Doublecortin is a 40kDa microtubule-associated protein (MAP) that is essential for migration of neurons during the development of the cerebral cortex. Mutations in the human DCX gene cause lissencephaly (smooth brain) or subcortical laminar heterotopia (SCLH), characterized by mental retardation and seizures. DCX interaction with MAPs stabilizes microtubules (MTs). The interaction with MTs is via a conserved N-terminal doublecortin (DC) domain. DCX can be regulated by phosphorylation at multiple sites by several kinases, including JNK, Cdk5, PKA, and MARK/PAR-1 family of protein kinases.

Physical form

Solution in 0.01 M phophate buffered saline, pH 7.4, containing 15 mM sodium azide.

Storage and Stability

For continuous use, store at 2-8 °C for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing, or storage in “frost-free” freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilutions should be discarded if not used within 12 hours.

The mammalian cortex is generally subdivided into six organized layers, which are formed during development in an organized fashion. This organized cortical layering is disrupted in case of mutations in the doublecortin (DCX) gene. DCX is a Microtubule Associated Protein

X-linked lissencephaly is a severe brain malformation affecting males. Recently it has been demonstrated that the doublecortin gene is implicated in this disorder. In order to study the function of Doublecortin, we analyzed the protein upon transfection of COS cells.

Repair of complex CNS circuitry requires newly incorporated neurons to become appropriately, functionally integrated. One approach is to direct differentiation of endogenous progenitors in situ, or ex vivo followed by transplantation. Prior studies find that newly incorporated neurons can establish

Doublecortin (DCX) is required for normal migration of neurons into the cerebral cortex, since mutations in the human gene cause a disruption of cortical neuronal migration. To date, little is known about the distribution of DCX protein or its function.

X-SCLH/LIS syndrome is a neuronal migration disorder with disruption of the six-layered neocortex. It consists of subcortical laminar heterotopia (SCLH, band heterotopia, or double cortex) in females and lissencephaly (LIS) in males, leading to epilepsy and cognitive impairment. We report
