The human epithelial antigen recognized monoclonal antibody (MAb) AUA1 has been characterized as a cell-surface glycoprotein. It has been isolated from human colonic mucosa by AUA1 affinity separation. N-terminal peptide sequence of this purified material has revealed a 17 amino acid sequence which identifies it with one of a group of similar epithelial/tumor-associated glycoproteins defined by a variety of MAbs. Using the polymerase chain reaction to map the gene encoding this antigen, our previous AUA1 antigen assignment to chromosome 2 has been confirmed.
