The GAP43 (Phospho-Ser41) antibody is a specialized tool used to detect the phosphorylated form of Growth-Associated Protein 43 (GAP43) at serine residue 41. GAP43. also known as B-50 or neuromodulin, is a neuron-specific protein highly expressed during axonal outgrowth, synaptic plasticity, and nerve regeneration. Its activity is closely linked to phosphorylation states, particularly at Ser41. a key regulatory site. Phosphorylation at this residue, mediated by protein kinase C (PKC), modulates GAP43's interaction with calmodulin and its role in intracellular signaling, ultimately influencing cytoskeletal dynamics and neurotransmitter release.
This antibody is widely employed in neuroscience research to study neuronal development, injury responses, and adaptive changes in the nervous system. By specifically recognizing the phosphorylated Ser41 epitope, it allows researchers to distinguish activated GAP43 from its non-phosphorylated form, providing insights into real-time signaling events. Common applications include Western blotting, immunohistochemistry, and immunofluorescence to map spatial-temporal phosphorylation patterns in brain tissues or cultured neurons. Its utility extends to investigating neurological disorders such as Alzheimer's disease, Parkinson's disease, and schizophrenia, where aberrant GAP43 phosphorylation has been implicated. Proper experimental controls, including phosphatase-treated samples, are essential to confirm specificity due to the transient nature of phosphorylation events.
