title: Amino acid sequence homology between the C3 chain of rat prostatic steroid binding protein and human alpha 2-macroglobulin.
abstract: Using a computer program designed to detect evolutionary relationships between proteins, I find that exon 2 of the C3 chain of rat prostatic steroid binding protein has amino acid sequence homology with residues 1058-1119 of the protease inhibitor alpha 2-macroglobulin. This finding suggests interesting approaches for studying the functions of these proteins.
