ZO-1 is a peripheral membrane protein that is associated with tight junctions (zonula occludentes), which are found on the cytoplasmic surfaces of epithelial and endothelial cell membranes. ZO-1 has a MW of 225 kD and is found in two isoforms that differ by the presence or absence of an 80 amino acid region known as 'motif-a'. These two isoforms are the basis for determining two classes of tight junctions (3). ZO-1 is known to interact with ZO-2. ZO-1 is homologous to dlg, the Drosophila tumor suppressor. Both are members of a putative signal transduction protein family whose members contain a SH3 domain and a domain homologous to the enzyme guanylate kinase.
