these studies indicate that the pre-s region encodes the 35,000 mr species , that this product accounts for the known polyalbumin-binding activity of hbsag but is not required for assembly and secretion of hbsag 22-nm particles , and that the major polypeptide of hbsag is not derived primarily by cleavage of larger precursors encoded by the pre-s region .
