Potent human p140-TrkA agonists derived from an anti-receptor monoclonal antibody.

Monoclonal antibody (mAb) 5C3 directed against human p140 TrkA is a structural and functional mimic of nerve growth factor (NGF) and an artificial receptor agonist. mAb 5C3 binds in the NGF-docking site and, like NGF, it promotes TrkA internalization, TrkA and phosphatidylinositol-3 kinase tyrosine phosphorylation, and increased transformation of TrkA… CONTINUE READING
