【 摘 要 】

A recombinant version of the receptor binding domain of rat α 1-macroglobulin (RBDv) consisting of residues 1319–1474 has been expressed in E. coli. Competition experiments with 125I-labelled methylamine treated human α 2-macroglobulin reveal that the α 1-macroglobulin-RBDv exhibit the same high affinity or the α 2-acroglobulin receptor as the entire 40 kDa light chain from rat α 1-macroglobulin. It is therefore concluded, that all determinants for receptor interaction reside in the C-terminal approx. 150 residues of the α-macroglobulin subunit.
