A region containing sites for ligand binding was localized in the 4525-amino acid residue
alpha 2-macroglobulin receptor/low density lipoprotein receptor-related protein (alpha
2MR/LRP) by ligand-and immunoblotting of proteinase and CNBr digests of the purified
human placental protein. 125I-Labeled rat alpha 1-macroglobulin light chain, urokinase-
plasminogen activator inhibitor type-1 complex, and alpha 2MR-associated protein all
bound to a 75-kDa CNBr-generated fragment (68 kDa after deglycosylation). In addition to …
