"However, the upregulation of TrkA tyrosine-490 phosphorylatin by NGF was significantly downregulated during the long-term inactivation of JNK caused by SP600125 treatment for 12 h, but not by wortmannin, suggesting a role of JNK in the maintenance of TrkA tyrosine-490 phosphorylation enhanced by NGF ( xref )."

"The addition of a copper extracellular chelator, as bathocuproine disulfonate (BCS), partially inhibited Tyr-490 phosphorylation of TrkA induced by both NGF and mimicking peptides, whereas a supplement of exogenous copper ions partially restored it.Differently, the reverse and scrambled peptides both in absence or presence of metal ions have no activity, confirming that the N-terminus sequence of protein is specifically involved in receptor interaction and metal binding specifically increase recognition process.The activation of TrkA by NGF or mimicking peptides triggered the signalling cascade of Akt and ERK."
