Antigen: phosphopeptide corresponding to amino acid residues surrounding phospho-Ser⁴¹ of Gap-43 · Host: rabbit · Application(s): WB · Gap-43 is thought to have an important role in development and plasticity because it is expressed at high levels in neuronal growth cones during development and during axonal regeneration.¹ There is also evidence from knockout animals that Gap-43 serves to amplify path finding signals from the growth cone.² Gap-43 is thought to mediate at least some of these effects via interaction with actin. Importantly, phosphorylation at Ser⁴¹ by protein kinase C (Catalog No. 1609-PKC) modulates the interaction of Gap-43 with actin and may also affect neurotransmitter release during forms of plasticity like LTP.^3,4
