Product Specifications

Immunogen

Phosphopeptide corresponding to amino acid residues surrounding the phospho-S41 of GAP-43

Specificity

Specific for the ~50 kDa GAP-43 protein phosphorylated at S41 in Western blots. In some tissues the antibody also recognizes a higher molecular weight protein, that is also recognized by the Pan GAP-43 antibody. This may be a GAP-43 aggregate or oligomer.

Clonality

Polyclonal

Host

Rabbit

IgG

Scientific Data Images for Phospho-GAP‑43 (S41) Antibody

Detection of Phospho-GAP-43 (S41) antibody by Western Blot.

Detection of Phospho-GAP‑43 (S41) by Western blot.

Western blot of rat cortex lysate showing specific immunolabeling of the ~50 kDa GAP-43 protein phosphorylated at S41 (Control). The phosphospecificity of this labeling is demonstrated by treatment with 1200 U of lambda Phosphatase ( lambda-PPase) for 30 minutes before being exposed to the Anti-Phospho-GAP-43 (S41). The immunolabeling is completely eliminated by treatment with lambda-PPase.

Background: GAP-43

GAP-43 (Growth Associated Protein 43 kDa), also known as Neuromodulin, is a 24 kDa, neuron growth cone-associated member of the neuromodulin family. Apparently due to its tertiary structure, it runs anomalously at 43 kDa on SDS-polyacrylamide gel. Rat GAP-43 is a 226 amino acid (aa) protein that contains an N-terminal lipid binding motif, an 11 aa IQ domain (IQ:Ile-Gln-X-Ser-etc) (aa 38 - 48), and a C-terminus with four potential serine phosphorylation sites. The molecule may utilize the IQ domain to bind calmodulin. Protein kinase C-mediated phosphorylation of the Serine at 41 within this site inhibits this interaction. Unphosphorylated, calmodulin-bound GAP-43 is always associated with neurite retraction, while S41 phosphorylated GAP-43 stabilizes actin filaments and promotes growth cone extension.
