The neurotrophin receptor tropomyosin-related kinase A (TrkA) is a receptor tyrosine kinase and belongs to the neurotrophic tyrosine kinase receptor (NTKR) family, the high-affinity binding partner of nerve growth factor (NGF). The kinase regulates responses to the neurotrophins NGF and NT3 in a wide variety of normal tissues and is critical for normal development and function of both nervous and immunological systems. NGF/TRKA signaling pathway has been implicated in normal myeloid progenitor cell function, differentiation, and survival, high levels of TRKA expression have been observed in myeloid malignancies.

Recombinant, human TRK-A (neurotrophic tyrosine kinase, receptor, type 1), protein kinase domain, C-terminal  fragment, amino acids G443-G796, recombinant and active enzyme, N-terminal GST-HIS6 fusion protein with a Thrombin and 3C cleavage site, expressed in Sf9 insect cells
