Protocol
Specificity / Sensitivity
Phospho-Doublecortin (Ser334) Antibody detects endogenous levels of doublecortin only when phosphorylated at Ser334.
Species Reactivity:
Human, Mouse, Rat
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser334 of doublecortin. Antibodies are purified by protein A and peptide affinity chromatography.
Background
Mutations in doublecortin (DCX) cause Lissencephaly (smooth brain), a neuronal migration disorder characterized by epilepsy and mental retardation (1). Doublecortin is a microtubule-associated protein that stabilizes and bundles microtubules. A conserved doublecortin domain mediates the interaction with microtubules, and interestingly most missense mutations cluster in this domain (2). Kinases JNK, CDK5, and PKA phosphorylate doublecortin. JNK phosphorylates Thr321, Thr331, and Ser334 while PKA phosphorylates Ser47 and CDK5 phosphorylates Ser297 (3-5). Phosphorylation of Ser297 lowers the affinity of doublecortin to microtubules. Furthermore, mutations of Ser297 result in migration defects (5).
Doublecortin phosphorylated at Ser334 is enriched in growth cones and affects neurite outgrowth and neuronal migration (3).
