Target Background

Function

TJP1, TJP2, and TJP3 are closely related scaffolding proteins that link tight junction (TJ) transmembrane proteins such as claudins, junctional adhesion molecules, and occludin to the actin cytoskeleton. The tight junction acts to limit movement of substances through the paracellular space and as a boundary between the compositionally distinct apical and basolateral plasma membrane domains of epithelial and endothelial cells. Necessary for lumenogenesis, and particularly efficient epithelial polarization and barrier formation. Plays a role in the regulation of cell migration by targeting CDC42BPBb to the leading edge of migrating cells. With TJP2 and TJP3, participates in the junctional retention and stability of the transcription factor DBPA, but is not involved in its shuttling to the nucleus.

Gene References into Functions

In the present study, organspecific expression of the tight junction proteins, claudin, occludin, junction adhesion molecule A and zona occludens 1 was examined in the canine duodenum, lung, liver and kidney. PMID: 27600198
Occludin and ZO-1 expression remained unchanged between atopic and clinically normal dogs. PMID: 25673908
ZO-1 knockout induced striking changes in myosin organization at cell-cell contacts and disrupted the localization of tight junction proteins. PMID: 25157572
Akt-dependent phosphorylation of Serine 373 increases gap junction size and communication by completely eliminating the interaction between Cx43 and ZO-1. PMID: 24213533
our study identifies alpha-catenin binding to ZO-1 as a new mechanism for coupling the assembly of the epithelial barrier to cell-to-cell adhesion. PMID: 23813953
ZO-1 and ZO-2 proteins are required not only for TJ assembly but also for regulating the organization and functional activity of the apical cytoskeleton, particularly the perijunctional actomyosin ring; these activities are relevant both to cellular organization and epithelial morphogenesis. PMID: 22190737
CPEB-mediated zonal occludens-1 mRNA localization is essential for tight-junction assembly and mammary epithelial cell polarity PMID: 22334078
ZO-1 and PLEKHA7 are paracingulin-interacting proteins that are involved in its recruitment to epithelial tight and adherens junctions, respectively PMID: 21454477
The results indicate that the transient interaction of afadin with ZO-1 is necessary for the formation of Tight junctions in MDCK cells. PMID: 20008323
Apg-2 regulates ZONAB function by competing for binding to the SH3 domain of ZO-1 and suggest that Apg-2 functions as a regulator of ZO-1-ZONAB signaling in epithelial cells in response to cellular stress. PMID: 16407410
These data reveal an unexpected function for the SH3 domain of ZO-1 in regulating tight junction assembly in epithelial cells. PMID: 16436508
a unique motif in the occludin sequence that is involved in the regulation of ZO-1 binding by reversible phosphorylation of specific Tyr residues. PMID: 19017651
Results provide the first direct evidence that ZO-1 limits solute permeability in established tight junctions, perhaps by forming a stabilizing link between the barrier and perijunctional actomyosin. PMID: 19605556
