Biochem/physiol Actions

TRKA (440-end), active, GST tagged human is a 140 kD membrane-spanning protein tyrosine kinase that belongs to proto-oncogene family. TRKA facilitates the regulation of cell differentiation and survival via activating SHC1 and FRS2 which in turn activates a GRB2-Ras-MAPK cascade. It also plays a pivotal role in controlling NF-κ-B activation as well as transcription of genes involved in cell survival via PLCG1.
