Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide surrounding Thr514 of human CRMP-2. Antibodies are purified by peptide affinity chromatography.

Collapsin Response Mediator Protein-2 (CRMP-2) is expressed at high levels in the developing nervous system and plays a critical role in axonal outgrowth by specifying axon/dendrite fate and establishing neuronal polarity (1,2). CRMP-2 enhances axon elongation and branching by binding to tubulin heterodimers to promote microtubule assembly (3). GSK-3β inactivates CRMP-2 by phosphorylating it at Thr514. CRMP-2 is primed following phosphorylation at Ser522 by CDK5 and at Thr518 by GSK-3β (2). Phosphorylation of CRMP-2, which decreases tubulin binding ability, can be inhibited by NT-3 and BDNF through the PI3 kinase/Akt pathway (2). CRMP-2 also mediates semaphorin-induced growth cone collapse (4). Hyperphosphorylation of CRMP-2 and is found in Alzheimer disease plaques with concurrent elevated GSK-3β activity in these patients (5).

Collapsin反应调节蛋白-2(CRMP-2)在神经系统的发育过程中高水平表达,在轴突生长中起着至关重要的作用,它决定轴突/树突的命运和建立神经元极性(1,2)。CRMP-2结合微管蛋白二聚体,促进微管组装,从而促进轴突伸长和分枝(3)。GSK-3β磷酸化CRMP-2的Thr514,使其失活。CRMP-2被CDK5在Ser522磷酸化,被GSK-3β在Thr518磷酸化(2)。CRMP-2的磷酸化,会降低其与微管蛋白结合的能力,可由NT-3和BDNF通过PI3激酶/ Akt的途径抑制(2)。CRMP-2也介导semaphorin诱导的生长锥崩溃(4)。CRMP-2的高磷酸化在阿尔茨海默病斑块中被发现,同时伴有升高的GSK-3β活性(5)。
