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.
Specificity
Natural and recombinant Mouse Tight junction protein ZO-1
Subcellular Location
Cell membrane Peripheral membrane protein Cytoplasmic side Cell junction tight junction Cell junction gap junction Cytoplasm myofibril sarcomere I band Moves from the cytoplasm to the cell membrane concurrently with cell-cell contact. Detected at the leading edge of migrating and wounded cells.
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 GCOM1.
