TrkA Protein (isoform 3) belongs to the nerve growth factor receptor family and can promote angiogenesis and has carcinogenic activity when overexpressed. TrkA Protein (isoform 3) antagonizes the anti-proliferative NGF-NTRK1 signaling that promotes the differentiation of neuronal precursors. TrkA Protein, Canine (HEK293, Fc) is the recombinant canine-derived TrkA protein, expressed by HEK293 , with N-hFc labeled tag.
