ZO-1 is a peripheral membrane protein that is associated with tight junctions (zonula occludentes) which are found on the cytoplasmic surface of epithelial and endothelial cell membranes.
ZO-1 has a MW of 225kD 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.
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.

Immunogen：A 69kD fusion protein corresponding to aa463-1109 of human ZO-1 cDNA. This sequence lies from the N-terminal to the 80aa region (the alpha-motif) present in the a+isoform but absent in the alpha- isoform due to alternative splicing.
