Structural similarity between the macrophage lectin specific for galactose/N-acetylgalactosamine and the hepatic asialoglycoprotein binding protein.
The rat peritoneal macrophage lectin specific for galactose/N-acetylgalactosamine was shown to be a homologue of the hepatic asialoglycoprotein binding protein (rat hepatic lectin, RHL). The macrophage lectin was immunochemically crossreactive with the major form of RHL (RHL-1) but not with the minor forms (RHL-2 and -3). The overall homology between the macrophage lectin and RHL-1 was confirmed by peptide maps of their lysyl endopeptidase digests on reverse-phase HPLC. Despite these similarities, however, the macrophage lectin was distinct from HRL-1 as revealed by the differences in the NH2-terminal 20 amino acid sequences of these two lectins.
