Localization of the heme-binding protein in the cytoplasm and of a heme-binding protein-like immunoreactive protein in the nucleus of rat liver parenchymal cells: immunocytochemical evidence of the subcellular distribution corroborated by radioimmunoassay and immunoblotting.


The abundant heme-binding protein of the liver, probably identical with Z-protein or liver fatty acid-binding protein, has an apparent molecular weight of 14,000 Da and is presumably involved in the intracellular transport of a variety of compounds. The cellular and subcellular distribution of HBP in the liver was studied in adult male and female rats by… (More)
