CRMP2 [p Ser522] Antibody

Western Blot: CRMP2 [p Ser522] Antibody [NBP3-23262] - Western blot image of mouse brain untreated (lanes 1 & 3) or treated with lambda phosphatase (lanes 2 & 4). The blot was probed with anti-CRMP2 (C-terminal Region) (lanes 1 & 2) or anti-CRMP2 (Ser-522) (lanes 3 & 4).

Immunocytochemistry/Immunofluorescence: CRMP2 [p Ser522] Antibody [NBP3-23262] - Immunocytochemical labeling of CRMP2 phosphorylation in aldehyde-fixed and NP-40-permeabilized NGF-differentiated PC12 cells. The cells were labeled with rabbit polyclonal anti-CRMP2 (Ser-522) (CP2191) antibody in the absence (Left) or presence (Right) of blocking peptide. The antibody was detected using appropriate secondary antibody conjugated to DyLight(R) 594.

CRMP2 [p Ser522] Antibody Summary

• Description: Stable for at least 1 year at -20°C.
• Immunogen: Phospho-CRMP2 (Ser-522) synthetic peptide (coupled to carrier protein) corresponding to amino acids surrounding Ser-522 in human CRMP2. This sequence is conserved in rat and mouse CRMP2, and has homology to the conserved site in CRMP1 and CRMP4, but is not conserved in CRMP3 and CRMP5. [UniProt# Q16555]
• Modification: p Ser522
• Specificity: The antibody detects a 70 kDa protein corresponding to the molecular mass of CRMP2 on SDS-PAGE immunoblots of human mouse brain, and this band is removed after lambda phosphatase treatment. In addition, this reactivity can be specifically blocked using phospho-CRMP2 (Ser-522) peptide (CX2195).

Background

Collapsin response mediator proteins (CRMPs) are cytosolic phosphoproteins involved in neuronal differentiation and axonal guidance. CRMP2 was previously shown to mediate the repulsive effect of Sema3A on axons and to participate in axonal specification. The CRMPs appear to play a complex role in axon growth as well as microtubule dynamics and axon induction. CRMPs localize to the lamellipodia and filopodia of axonal growth cones, suggesting a role in axon guidance. Moreover, CRMP2 is upregulated after axotomy, and appears to increase the formation of axon-type processes from hippocampal neurons. CRMP2 has been reported to bind tubulin dimers directly and modulate microtubule assembly. CRMPs have also been implicated in the pathogenesis of a paraneoplastic neurologic syndrome. Interaction studies have implicated phospholipase D2 (PLD2), the cytosolic tyrosine kinase Fes, and intersectin in CRMP function. Hyperphosphorylation of CRMP2 is an early event in the progression of Alzheimer's disease.
