- Abstract
Four cDNAs extending into the 5'-noncoding region of the human von Willebrand factor cDNA have been characterized. Thirty-four residues of amino-terminal protein sequence for von Willebrand antigen II matched that predicted from the cDNA sequence, confirming that the propeptide of von Willebrand factor is von Willebrand antigen II. Among the known cDNA sequences there are four confirmed single nucleotide differences, of which two may be in linkage disequilibrium, and two would alter the protein sequence. Based on comparisons among the four repeated D domains, an evolutional model has been proposed to account for the distribution of these sequence elements in prepro-von Willebrand factor.
