ZO-1 / TRP channels
Name: Tight junction protein ZO-1
(ZO-1)
Official Symbol: TJP1
provided by HGNC
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.
