ZO-1 Antibody – Rat Monoclonal

Function: The N-terminal may be involved in transducing a signal required for tight junction assembly, while the C-terminal may have specific properties of tight junctions. The alpha domain might be involved in stabilizing junctions. Plays a role in the regulation of cell migration by targeting CDC42BPB to the leading edge of migrating cells

By similarity.

Subunit structure: Homodimer, and heterodimer with TJP2/ZO-2 and TJP3/ZO-3. Interacts with CGN/cingulin, CALM, CXADR, GJD3, HSPA4 and UBN1. Interacts (via ZU5 domain) with CDC42BPB. Interacts (via PDZ domain) with GJA1

By similarity. Interacts with OCLN, claudins, GJA12 and KIRREL1. Interacts with BVES (via the C-terminus cytoplasmic tail). Interacts (via ZU5 domain) with MYZAP. Interacts (via PDZ domains) with ANKRD2
