Characterization of human stellate cell activation-associated protein and its expression in human liver

This study cloned cDNA of human homologue (hSTAP) of rat stellate cell activation-associated protein (rSTAP). hSTAP gene is on chromosome 17q and is composed of four exons. Various types of cells including hepatic stellate cells expressed hSTAP mRNA. Recombinant hSTAP was a heme protein with the activity of peroxidase. hSTAP can be used as a marker of quiescent stellate cells in human liver. (C) 2002 Elsevier Science B.V. All rights reserved.
