Rat prostatic binding protein genes C1, C2, and C3 were mapped on rat chromosome 5 by in situ hybridization on rat peripheral blood chromosome preparations using three different cDNA probes. Of the grains detected, 15.9%, 25.2%, and 19.6%, respectively, mapped to chromosome 5. For each probe, the label was predominantly located on 5q31, but for C2 and C3 an additional site on 5q21 was found. The results suggest that three genes coding for the different polypeptide chains of rat prostatic binding protein map to the same chromosome and presumably to the same chromosome band.
