TFRC is a key protein in cellular iron uptake, coordinating receptor-mediated endocytosis of the ligand transferrin into specialized endosomes, where endosomal acidification triggers iron release. TFRC actively regulates T and B cell proliferation through iron uptake. TFRC Protein, Cynomolgus (HEK293, His) is the recombinant cynomolgus-derived TFRC protein, expressed by HEK293 , with N-His labeled tag.
