The precise location of the 3' ends of the chicken pro alpha 2(I) collagen gene have been identified by S1 nuclease protection of overlapping genomic fragments by calvaria poly A containing RNA and size determination of the protected fragments on DNA sequencing gels. The gene ends 300 and 306 bp and 754 and 777 bp from the translation stop codon. The two sets of ends explain the major and minor pro alpha 2(I) collagen mRNAs previously observed, which may result from either RNA polymerase readthrough of the first termination site and/or different processing sites.
